Ethical Supply Chains in 2026: HR, ILO Standards, UNGPs, ETI

ILO Labour Standards, UN Guiding Principles, the ETI Base Code, Modern Slavery Due Diligence — and Why Audits Are Not Enough

The supplier passed the audit. so why are workers still at risk?

A supplier passes a social audit. The file looks reassuring: policies are present, payroll samples have been checked, health-and-safety posters are on the wall, and management has signed the corrective action plan. Three months later, workers report excessive overtime, recruitment fees, intimidation by supervisors, unsafe machinery, wage deductions, cramped accommodation and retaliation after raising concerns.

This is the audit paradox: the organisation has compliance evidence, but workers still experience harm.

The problem is not that audits are always useless. The problem is that an audit is a limited evidence-gathering tool, not proof that labour rights are respected. A supplier can pass an audit because workers are afraid to speak, records are incomplete, excessive overtime is hidden, recruitment debt sits outside the factory, subcontracting is undisclosed, or purchasing pressure from the buyer makes legal compliance commercially difficult.

The central question for people professionals is therefore not:

“Did the supplier pass the audit?”

It is:

“What are the actual risks to workers, what caused them, who experiences them, what evidence do we have, what are we doing about it, and are workers seeing improvement?”

This resource follows the progression:

LABOUR RIGHTS → HUMAN RIGHTS → RISK → DUE DILIGENCE → WORKER VOICE → AUDIT → ROOT CAUSE → REMEDIATION → ACCOUNTABILITY.

Why this matters to people professionals

Ethical supply chains are often treated as procurement, compliance or ESG issues. That is too narrow. Supply-chain labour risks are people risks. They concern wages, working hours, recruitment, discrimination, freedom of association, voice, safety, discipline, grievance, capability, culture and leadership.

People professionals are relevant because they understand:

how employment systems create or reduce vulnerability;
how incentives shape line-manager behaviour;
how grievance channels succeed or fail;
how culture affects whether workers speak up;
how workforce data can reveal risk;
how recruitment and agency labour can create exploitation;
how leadership accountability affects implementation.

The ILO states that labour rights are human rights and that human-rights due diligence involves identifying, preventing, mitigating and accounting for actual and potential impacts, with meaningful consultation with affected groups, worker organisations and social dialogue [1]. This makes ethical supply chains a core people-management concern, not an optional CSR activity.

What is an ethical supply chain?

An ethical supply chain is one in which an organisation identifies and addresses risks to people across its business relationships, respects internationally recognised labour and human rights, uses purchasing and governance practices that do not create harm, listens to affected workers, provides or enables remedy, and demonstrates improvement over time.

An ethical supply chain is not defined by a supplier code alone. Nor is it defined by a single audit, a certification badge or a modern slavery statement. It requires continuous practice across six dimensions:

Dimension	Practical meaning
Rights	Workers’ fundamental labour and human rights are recognised.
Risk	The organisation prioritises risks to people, not only risks to the business.
Voice	Workers can speak freely, safely and collectively.
Behaviour	Buyer purchasing practices support, rather than undermine, decent work.
Remedy	Harm is corrected and affected workers are restored as far as possible.
Accountability	Senior leaders, HR, procurement, legal, ESG and operations share responsibility.

The ILO foundation

The International Labour Organization’s Declaration on Fundamental Principles and Rights at Work identifies five categories of fundamental principles and rights [2]:

Freedom of association and the effective recognition of the right to collective bargaining
Key conventions: Convention No. 87 and Convention No. 98.
Elimination of all forms of forced or compulsory labour
Key conventions: Convention No. 29, Convention No. 105, and the 2014 Protocol to Convention No. 29 [11].
Effective abolition of child labour
Key conventions: Convention No. 138 and Convention No. 182.
Elimination of discrimination in respect of employment and occupation
Key conventions: Convention No. 100 and Convention No. 111.
A safe and healthy working environment
Added as a fundamental principle in 2022, with key conventions including Convention No. 155 and Convention No. 187 [2].

These principles matter because they are not merely “nice to have” standards. They are the labour-rights foundation for assessing whether work is decent, safe, free, non-discriminatory and capable of collective representation.

The ILO is not just a checklist

A weak use of ILO standards treats them as audit headings. A stronger use asks how employment systems either respect or undermine rights.

For example:

ILO principle	Checklist question	Stronger due-diligence question
Freedom of association	Is there a policy?	Can workers organise without intimidation, dismissal, blacklisting or retaliation?
Forced labour	Are workers free to leave?	Are workers trapped by debt, deposits, document retention, threats or recruitment fees?
Child labour	Are ages checked?	What household, wage, subcontracting or seasonal pressures make child labour more likely?
Discrimination	Is there an equal opportunities policy?	Who is concentrated in the lowest-paid, most insecure or least protected roles?
Safe and healthy work	Are safety records available?	Do production targets, overtime and fear of discipline lead workers to accept unsafe work?

The ILO’s labour-dimension guidance on human-rights due diligence emphasises meaningful consultation, worker organisations and social dialogue [1]. This moves organisations beyond paperwork into lived experience.

The un guiding principles on business and human rights

The UN Guiding Principles on Business and Human Rights are built around the Protect–Respect–Remedy framework [8][9][10]:

State duty to protect human rights.
Corporate responsibility to respect human rights.
Access to remedy for people harmed by business-related impacts.

For companies, the UNGPs require a human-rights due-diligence approach that includes:

identifying and assessing actual and potential human-rights impacts;
integrating findings and taking action;
tracking effectiveness;
communicating how impacts are addressed [10].

The UNGPs also distinguish how a company may be connected to harm:

Connection to harm	Meaning	Practical implication
Cause	The company’s own actions create the harm.	Stop the harm and provide or cooperate in remedy.
Contribute	The company’s actions help cause or worsen the harm.	Stop contribution, use leverage and contribute to remedy.
Direct linkage	Harm is linked to operations, products or services through a business relationship.	Use leverage to prevent or mitigate harm; remedy expectations depend on involvement.

This distinction is essential for people professionals. If buyer purchasing practices drive excessive overtime, the buyer may be contributing to harm rather than merely observing supplier non-compliance.

Human rights due diligence vs social auditing

Human-rights due diligence and social auditing are often confused. They are not the same.

Feature	Social audit	Human-rights due diligence
Core purpose	Check compliance against a standard	Identify, prevent, mitigate, remediate and account for impacts
Frequency	Often periodic	Continuous and risk-based
Evidence	Documents, interviews, site observation	Multiple sources, including worker voice, grievance data, purchasing data and context
Focus	Supplier performance	Impacts on people and the company’s connection to them
Risk lens	Often business and compliance risk	Severity of harm to people
Outcome	Pass/fail, rating, corrective action plan	Prevention, mitigation, remedy, leverage, governance and learning

The ILO describes due diligence as identifying, preventing, mitigating and accounting for actual and potential impacts [1]. Peer-reviewed research also cautions that HRDD can be weakened by superficial implementation, weak enforcement, limited worker participation and insufficient attention to power relations in supply chains [12].

The ETI base code

The Ethical Trading Initiative Base Code is a widely used labour code founded on ILO standards [3]. Its nine clauses are:

Employment is freely chosen.
Freedom of association and the right to collective bargaining are respected.
Working conditions are safe and hygienic.
Child labour shall not be used.
Living wages are paid.
Working hours are not excessive.
No discrimination is practised.
Regular employment is provided.
No harsh or inhumane treatment is allowed.

The ETI Base Code is useful because it translates broad labour rights into operational expectations. However, it remains a standard. It does not, by itself, prove that workers experience decent work. Implementation, evidence and worker outcomes matter.

ILO vs UNGP vs ETI base code

Framework	What it is	Main contribution	Limitation if misused
ILO standards	International labour principles and conventions	Defines fundamental labour rights	Can be reduced to checklist compliance
UNGPs	Global business and human-rights framework	Explains corporate responsibility, due diligence, leverage and remedy	Can become abstract if not operationalised
ETI Base Code	Practical labour code	Converts labour standards into supplier requirements	Can become audit-focused rather than worker-focused

A mature ethical supply-chain system uses all three:

ILO defines the labour-rights foundation.
UNGPs define the due-diligence logic.
ETI Base Code supports operational supplier expectations.

Modern slavery

Modern slavery is an umbrella term covering severe exploitation, including forced labour, human trafficking, slavery and servitude. The UK Home Office guidance explains modern slavery concepts and notes the global estimate of 27.6 million people in forced labour, sourced to ILO, Walk Free and IOM estimates [7].

Modern slavery risk is not limited to criminal networks. It can be produced by ordinary business systems: low prices, urgent orders, labour brokers, migration debt, weak grievance channels, informal subcontracting and fear of dismissal.

Key indicators include:

recruitment fees or debt bondage;
document retention;
threats, intimidation or violence;
restriction of movement;
deceptive recruitment;
wage withholding or illegal deductions;
excessive overtime under threat;
dependency on employer-provided housing;
retaliation for complaints.

Modern slavery risk in supply chains

Modern slavery risk increases where workers have low power and employers or intermediaries have high control.

Common contextual risk factors include:

Risk factor	Why it matters
Migrant or temporary labour	Workers may depend on employers for visas, housing, transport or legal status.
Labour brokers	Fees, deception and fragmented accountability can occur before employment begins.
Piece-rate or seasonal work	Income insecurity can hide excessive hours or child labour risk.
Informal subcontracting	The buyer may not know where work is actually performed.
Remote worksites	Isolation reduces visibility and access to remedy.
Weak labour inspection	Public enforcement may be limited.
Gender, caste, ethnicity or migration status	Discrimination can concentrate vulnerability.
Low prices and urgent lead times	Suppliers may pass pressure onto workers through overtime, wage deductions or unsafe work.

The ethical question is not whether a country or sector is “bad”. It is whether specific operating conditions create foreseeable risks to specific groups of workers.

Responsible recruitment

Responsible recruitment means workers should not pay for a job, should receive accurate information, should keep control of identity documents, and should be able to leave employment without coercion.

People professionals should pay particular attention to:

recruitment fees charged by agents or sub-agents;
deductions for transport, accommodation, tools or documentation;
contract substitution;
language barriers;
visa dependency;
passport or identity-document retention;
repayment clauses that trap workers;
use of temporary, agency or outsourced labour.

A responsible recruitment system should include:

mapping all recruiters and sub-agents;
contract clauses prohibiting worker-paid fees;
worker interviews before and after arrival;
repayment procedures where fees are found;
monitoring of deductions and debt indicators;
grievance channels accessible to migrant workers;
consequences for non-compliant labour providers.

The purchasing practices problem

Ethical supply-chain failures are often attributed to “bad suppliers”. That is incomplete. Buyer behaviour can create the conditions in which suppliers cut corners.

Risk-creating purchasing practices include:

prices below the cost of legal and decent production;
last-minute order changes;
unrealistic lead times;
penalties for delay without shared planning;
inaccurate forecasting;
short-term contracts that discourage investment;
failure to pay on time;
demand peaks that require excessive overtime;
ignoring wage, safety or recruitment costs during negotiation.

If procurement rewards lowest cost and fastest delivery while HR promotes decent work, the organisation sends contradictory signals. A supplier code that says “working hours must not be excessive” is undermined if the buyer repeatedly places urgent orders that can only be met through excessive overtime.

The audit problem

Social audits can identify visible non-compliance, but they have well-known limitations:

Limitation	Why it matters
Announced or predictable visits	Suppliers can prepare records and coach workers.
Short duration	Auditors may not understand seasonal, subcontracted or night-shift realities.
Document reliance	Records may be incomplete, falsified or not cover informal labour.
Fearful interviews	Workers may not speak honestly if retaliation is likely.
Management control	Auditors may be guided to selected areas or workers.
Narrow scope	Recruitment, accommodation, homeworking or subcontracting may be missed.
Corrective-action closure	A document may be closed without real improvement.

Research on social-compliance systems highlights risks of decoupling, where formal compliance structures exist but are disconnected from day-to-day practice [13]. This reinforces the need to treat audits as one evidence source, not the evidence source.

Why worker voice matters

Worker voice is the bridge between compliance evidence and lived reality.

Workers are often the first to know when:

overtime is coerced;
deductions are unlawful;
supervisors intimidate staff;
safety equipment is unavailable;
recruitment agents charged fees;
grievance channels are unsafe;
union activity is discouraged;
audit interviews are coached.

Meaningful worker voice includes individual and collective channels. The ILO emphasises consultation with affected groups, worker organisations and social dialogue [1]. Freedom of association and collective bargaining are therefore not peripheral: they are core risk controls.

Good worker voice is:

accessible in workers’ own languages;
trusted by workers;
protected from retaliation;
available to agency, migrant and temporary workers;
connected to remedy;
analysed for patterns, not only individual complaints;
independent enough to surface uncomfortable information.

Grievance mechanisms

A grievance mechanism is not a suggestion box. Under the UNGP logic, grievance mechanisms should help identify and address harm and support access to remedy [10].

Effective grievance mechanisms should be:

Criterion	Practical test
Legitimate	Do workers trust that the process is fair?
Accessible	Can all workers use it, including migrants, women, agency workers and low-literacy workers?
Predictable	Are timelines and steps clear?
Equitable	Can workers access advice and support?
Transparent	Are outcomes communicated without breaching confidentiality?
Rights-compatible	Do outcomes respect labour and human rights?
Learning-oriented	Are root causes identified?
Based on dialogue	Are affected workers involved?

Warning signs include low complaint numbers in a high-risk site, repeated anonymous complaints, retaliation rumours, unresolved wage issues, and grievance data that is not reviewed by senior leaders.

Remediation

Remediation means addressing harm experienced by workers. It is not the same as terminating a supplier relationship or updating a policy.

Remedy may include:

repayment of recruitment fees;
reimbursement of unlawful deductions;
payment of wage arrears;
medical care after injury;
reinstatement or compensation after retaliation;
safe transfer from exploitative accommodation;
correction of contracts;
reduction of excessive working hours without wage loss where possible;
supervisor discipline or retraining;
recognition of worker representatives;
non-repetition measures.

A credible remediation plan asks:

Who was harmed?
What harm occurred?
What caused it?
What does the affected worker want?
What remedy is appropriate?
Who pays?
How will retaliation be prevented?
How will recurrence be monitored?

The UK Home Office guidance encourages meaningful engagement and victim-centred remediation in modern slavery responses [7].

The root-cause problem

A corrective action plan often treats symptoms. Root-cause analysis asks why the harm happened.

Symptom	Weak correction	Root-cause analysis
Excessive overtime	“Supplier to reduce hours”	Are lead times, forecasting, wages, production planning or staffing levels driving overtime?
Recruitment fees	“Agency warned”	How are agents selected, paid and monitored? Are workers reimbursed?
Wage deductions	“Payroll corrected”	Are deductions linked to accommodation, tools, loans, transport or disciplinary systems?
Safety breach	“Training completed”	Are targets, machine maintenance, PPE budgets or supervisor incentives creating unsafe work?
Retaliation	“Manager reminded of policy”	Is there a culture of fear? Are complaints independent? Are unions respected?

Root causes frequently sit across organisational boundaries. Procurement, HR, operations and finance may all contribute.

Supplier exit vs responsible engagement

Exiting a supplier may be necessary where there is severe harm, deception, refusal to remediate or danger to workers. But immediate exit can also worsen harm if workers lose income, remedy is abandoned, or the supplier shifts production to less visible buyers.

Responsible engagement means using leverage before, during and after decisions:

Situation	Better response
Supplier lacks capability but is transparent	Support improvement with clear milestones.
Supplier hides serious harm	Escalate, investigate, protect workers and consider suspension or exit.
Harm is linked to buyer pressure	Change purchasing practices, not only supplier behaviour.
Workers are owed money	Ensure repayment before exit where possible.
Retaliation risk exists	Put worker protection before commercial disengagement.

The key judgement is whether continued engagement is likely to reduce harm. If engagement becomes a cover for inaction, exit may be justified. If exit abandons affected workers, it is not responsible.

Supplier capability

Many suppliers need capability, not only policing. Capability building may include:

HR systems for contracts, payroll and working-time management;
responsible recruitment procedures;
supervisor training on respectful management;
occupational safety systems;
grievance handling;
worker-representative engagement;
production planning;
accommodation standards;
data collection and reporting;
remediation protocols.

Capability building should not become an excuse for tolerating abuse. It must be linked to measurable outcomes, worker feedback and time-bound expectations.

The role of people professionals

People professionals can add value by shifting the organisation from compliance administration to workforce-risk intelligence.

Key contributions include:

Embedding labour rights into people strategy.
Assessing recruitment and agency-labour risk.
Reviewing supplier HR systems.
Designing worker-voice and grievance expectations.
Training procurement and supplier managers.
Analysing workforce data for red flags.
Supporting remediation after harm.
Challenging incentives that drive poor labour practices.
Linking executive reward to responsible-business outcomes.
Ensuring lessons from supply chains inform internal people practice.

People professionals should not claim ownership of all supply-chain risk. They should ensure labour expertise is present in governance.

HR and procurement must work together

Ethical supply-chain management fails when procurement, HR, legal, ESG and operations work in silos.

Function	Typical focus	Ethical supply-chain contribution
HR/People	Work, culture, voice, capability	Labour-rights expertise, grievance, recruitment, training
Procurement	Suppliers, cost, delivery	Purchasing practices, leverage, contracts, supplier engagement
Legal	Liability, contracts, regulation	Clauses, disclosure, investigations, legal risk
ESG/Sustainability	Reporting, standards, stakeholders	Frameworks, metrics, external accountability
Operations	Production, quality, timing	Forecasting, technical feasibility, workload
Finance	Budgets, payment terms	Costing decent work, payment discipline

A practical governance model includes:

board or executive oversight;
cross-functional risk committee;
named senior owner;
escalation procedure for severe harm;
procurement-HR sign-off for high-risk sourcing;
supplier improvement budget;
worker-remediation fund or protocol;
dashboard reviewed quarterly.

Modern slavery due-diligence cycle

A practical due-diligence cycle is continuous:

Map suppliers, labour providers, subcontractors, worksites and worker groups.
Identify risks using country, sector, workforce, recruitment and purchasing data.
Prioritise severe risks to people.
Assess actual conditions through audits, worker voice, document review, grievance data and independent intelligence.
Prevent and mitigate through purchasing changes, supplier capability, responsible recruitment and controls.
Remediate harm where workers have been affected.
Track effectiveness using worker outcomes, not only activity measures.
Communicate and report accurately, distinguishing actions from results.
Review governance and adjust incentives, contracts and accountability.

This aligns with the UNGP and ILO conception of due diligence as an ongoing process rather than a one-off compliance exercise [1][10].

Risk-based due diligence

Risk-based due diligence prioritises the most severe risks to people. It is not simply a ranking of reputational, financial or legal risks to the organisation.

Key prioritisation factors include:

Factor	Question
Scale	How serious is the harm?
Scope	How many people may be affected?
Irremediability	Can the harm be put right, or is it permanent?
Likelihood	How probable is the harm given context and evidence?
Severity	Combining scale, scope and irremediability, which risks require urgent action?

Example: a low-probability risk of forced labour affecting migrant workers may outrank a high-probability risk of minor payroll error because the severity is greater.

The 2026 regulatory landscape

Legal disclaimer: Applicability depends on entity size, sector, jurisdiction, turnover, group structure, supply-chain role and current official guidance. Distinguish carefully between law in force, implementation deadlines, policy guidance, proposed or amended texts, and voluntary standards. This section is educational, not legal advice.

European union

The Council of the EU announced on 24 February 2026 that it had given final green light to an Omnibus simplification package affecting sustainability reporting and due-diligence requirements [4]. The Council press release states that:

CSRD scope is raised to companies with more than 1,000 employees and more than €450 million turnover, with third-country thresholds described by the Council [4].
CS3D scope is raised to companies with more than 5,000 employees and more than €1.5 billion turnover [4].
Due diligence is to focus on likely adverse-impact areas using reasonably available information [4].
The harmonised civil-liability regime and climate transition-plan duty are removed, according to the Council press release [4].
National penalties are capped at 3% of worldwide turnover [4].
The transposition deadline is stated as 26 July 2028, with company compliance from July 2029 [4].
The text enters into force after publication in the Official Journal [4].

Directive (EU) 2026/470 and the consolidated version of Directive (EU) 2024/1760 should be checked for the operative legal text and current consolidation [5][6].

United kingdom

The UK Modern Slavery Act 2015 section 54 transparency duty remains distinct from a mandatory human-rights due-diligence statute. The Home Office guidance states that section 54 applies to qualifying commercial organisations that carry on business in the UK, supply goods or services, and meet the £36 million turnover threshold [7]. It requires an annual slavery and human trafficking statement, with website publication, a homepage link, board approval and director or LLP member signature requirements described in the guidance [7].

The guidance encourages meaningful engagement and victim-centred remediation, but the transparency duty is not the same as a mandatory HRDD regime [7].

Other jurisdictions

National regimes and reporting duties may apply in countries including France, Germany, Norway, Switzerland, Australia, Canada and others. Applicability varies. Organisations should verify current official legal requirements in each relevant jurisdiction rather than assuming that one global standard satisfies all duties.

Mandatory due diligence vs voluntary standards

Feature	Mandatory due-diligence law	Voluntary standard
Source	Statute or regulation	Multi-stakeholder, industry or company standard
Enforceability	Legal consequences may apply	Contractual, reputational or membership consequences
Scope	Defined by law	Defined by code, scheme or company
Evidence	Legal compliance evidence required	Implementation evidence expected
Examples in this resource	EU due-diligence developments; UK section 54 transparency duty	ETI Base Code; supplier codes

Voluntary standards remain valuable. They can define expectations, support supplier training and create consistency. But they do not replace legal obligations where those apply.

The “audit passed — so we’re safe” fallacy

The fallacy has three parts:

Evidence fallacy: audit evidence is treated as full reality.
Responsibility fallacy: supplier non-compliance is treated as separate from buyer behaviour.
Closure fallacy: corrective-action closure is treated as worker remedy.

A passed audit may mean:

the site complied with sampled requirements on the audit day;
records appeared acceptable;
workers interviewed did not disclose problems;
issues outside scope were not identified.

It does not prove:

no forced labour;
no recruitment-fee debt;
no retaliation;
no hidden subcontracting;
no excessive overtime during peak season;
no discrimination;
no unsafe conditions;
no harm in accommodation or labour-provider systems.

A mature organisation asks what the audit could not see.

What good evidence looks like

Good evidence is triangulated, worker-centred and outcome-focused.

Evidence level	Examples	Strengths	Risks
Policy evidence	Supplier code, contracts, HR policies	Shows expectations	Says little about practice
Process evidence	Training, procedures, audit plans	Shows activity	May become box-ticking
Compliance evidence	Payroll, hours, age checks, safety records	Useful for verification	Can be incomplete or manipulated
Worker evidence	interviews, surveys, unions, grievance data	Reveals lived reality	Requires trust and anti-retaliation safeguards
Outcome evidence	fee repayment, reduced injuries, wage correction, lower excessive overtime	Shows change	Needs baseline and follow-up
Independent/context evidence	civil society, unions, official data, credible research	Adds external perspective	Must be assessed for relevance and quality

A strong evidence file includes both what the organisation did and whether workers are better off.

Supply-chain data people professionals should watch

People professionals should help build a labour-risk dashboard.

Indicator	Red flag
Overtime hours	Peaks linked to buyer order changes
Wage deductions	Deductions for recruitment, accommodation, tools or loans
Labour turnover	High turnover in one group or season
Recruitment source	Heavy use of brokers or sub-agents
Worker-paid fees	Any fee indicator or debt report
Grievance volume	Zero complaints in a high-risk site
Retaliation reports	Complaints followed by dismissal, transfer or threats
Injury and near-miss data	Under-reporting or sudden drops after audit
Agency-worker ratio	High proportion of insecure workers
Migrant-worker concentration	Dependency on employer housing or visas
Subcontracting	Unapproved or unexplained capacity increases
Payment terms	Late buyer payment linked to wage delay
Lead-time changes	Frequent urgent amendments
Audit findings recurrence	Same issue reappears after closure
Worker survey trust scores	Low confidence in grievance channels

Worked case studies

Case 1: garment supplier and excessive overtime

A fashion buyer places repeated late orders with short lead times. The supplier passes an annual audit, but worker interviews through an independent channel reveal 72-hour weeks, coached audit responses and fear of dismissal for refusing overtime.

Weak response: require the supplier to “comply with working-hours law” and close the corrective action after a policy update.

Stronger response: identify buyer contribution through forecasting and lead-time practices; review prices and capacity planning; monitor working hours during peak periods; protect workers from retaliation; involve worker representatives; adjust purchasing KPIs; track whether overtime falls without wage loss.

Level 7 judgement: the supplier is responsible for legal compliance, but the buyer may contribute to the conditions causing excessive overtime. Ethical action requires changing both supplier management and buyer purchasing behaviour.

Case 2: agricultural labour and recruitment fees

A food company sources from farms using migrant seasonal labour. Workers report deductions for transport and recruitment, overcrowded housing and threats of non-renewal if they complain.

Weak response: ask the labour provider to sign a no-fees declaration.

Stronger response: map labour providers and sub-agents; interview workers confidentially in their language; reimburse fees; review accommodation; amend labour-provider contracts; create safe grievance channels; monitor deductions; involve procurement, HR and legal in escalation.

Level 7 judgement: modern slavery risk is heightened by migrant status, labour intermediaries, dependency and isolation. A responsible response prioritises repayment, protection and prevention, not only contractual assurance.

The people professional’s 10 questions

Which workers in our supply chain are most vulnerable, and why?
Do our purchasing practices make decent work commercially possible?
Are workers paying recruitment fees anywhere in the chain?
Can workers organise, bargain and complain without retaliation?
What do workers say that audits do not show?
Which risks are most severe to people, not just to the business?
Where might we cause, contribute to or be directly linked to harm?
What remedy is available when harm occurs?
What evidence shows that conditions have improved?
Who is accountable at senior level for labour-rights outcomes?

Level 7 critical analysis

Level 7 analysis should move beyond description. It should evaluate tensions, mechanisms, evidence quality and practical implications.

A strong answer:

defines key concepts accurately;
uses ILO, UNGP and ETI frameworks appropriately;
distinguishes compliance from due diligence;
analyses power relations between buyer and supplier;
evaluates audit limitations without dismissing audits entirely;
considers worker voice and retaliation risk;
links modern slavery to recruitment, migration and purchasing systems;
weighs exit against engagement;
distinguishes legal duties from voluntary standards;
makes a justified practical judgement.

A weak answer says: “The company should audit suppliers and ensure compliance.”
A strong answer asks: “What risk to which workers, caused by what system, evidenced how, remediated by whom, and governed through what accountability?”

Level 7 command word guide

Command word	What to do
Analyse	Break the issue into causes, mechanisms and consequences.
Evaluate	Judge strengths, weaknesses and trade-offs using evidence.
Critically discuss	Present arguments, counterarguments and a reasoned position.
Assess	Weigh significance, severity or effectiveness.
Compare	Identify similarities and differences and explain why they matter.
Recommend	Propose feasible action linked to diagnosis and evidence.
Justify	Explain why your recommendation is better than alternatives.
Synthesize	Connect multiple frameworks into one coherent argument.
Reflect	Consider implications for professional practice and accountability.

Model level 7 paragraph

Claim: Social audits are insufficient as a primary ethical supply-chain control because they provide partial compliance evidence rather than reliable evidence of workers’ lived experience.
Evidence: The ILO frames due diligence as identifying, preventing, mitigating and accounting for actual and potential impacts, with meaningful consultation and social dialogue [1], while research on compliance systems highlights risks of decoupling between formal structures and practice [13].
Mechanism: Audits may miss hidden recruitment fees, coerced overtime, retaliation or subcontracting because workers fear speaking, records can be incomplete and buyer purchasing pressure may sit outside the audit scope.
Limitation: Audits can still be useful when targeted, independent and combined with document review, site observation and worker interviews.
Counterargument: Some organisations argue that audit coverage is necessary for scale and comparability.
Practical implication: The appropriate response is not to abandon audits but to embed them within risk-based HRDD, worker voice, grievance mechanisms, purchasing-practice reform and remediation.
Judgement: Therefore, a passed audit should be treated as one data point, not assurance that labour rights are respected.

Weak vs strong writing

Weak writing	Strong writing
Suppliers should be ethical.	Buyers must examine how their own pricing, lead times and order changes affect supplier labour conditions.
The audit showed compliance.	The audit provides limited evidence and must be triangulated with worker voice, grievance and payroll data.
Modern slavery happens in poor countries.	Modern slavery risk arises from vulnerability, coercion, recruitment debt and weak accountability across contexts.
The company should follow the ILO.	The company should operationalise the ILO’s five fundamental principles through contracts, purchasing, worker voice and remediation.
The UNGPs are about human rights.	The UNGPs require companies to assess impacts, act, track effectiveness and communicate, using cause, contribution and linkage analysis.
The ETI Code proves ethical sourcing.	The ETI Base Code defines expectations but does not prove implementation or worker outcomes.
Workers can use the hotline.	The organisation must test whether workers trust the channel, can access it safely and receive remedy.
The supplier is responsible.	Supplier responsibility must be assessed alongside buyer leverage and purchasing practices.
Exit unethical suppliers.	Exit may be necessary, but responsible engagement may better protect workers where remedy is still possible.
Recruitment agencies signed a policy.	Fee-free recruitment must be verified through worker interviews, deduction checks and repayment mechanisms.
No complaints means no problems.	No complaints in a high-risk site may indicate fear, inaccessibility or lack of trust.
Training solved the issue.	Training is only credible if behaviour and worker outcomes change.
The law requires ethical supply chains.	Legal duties vary by jurisdiction; voluntary standards and HRDD expectations must be distinguished from binding law.
Forced labour is rare.	Forced labour indicators may be hidden in debt, deductions, threats, document retention and dependency.
We need more audits.	We need better evidence, risk prioritisation, worker voice, root-cause analysis and accountability.

FAQ

1. Is an ethical supply chain the same as a compliant supply chain?
No. Compliance is part of ethical practice, but ethical supply-chain management also requires risk analysis, worker voice, purchasing-practice reform, remediation and accountability.

2. Are audits useless?
No. Audits can provide useful evidence, but they are limited and should not be treated as proof that workers are safe.

3. What is the difference between labour rights and human rights?
Labour rights are human rights. The ILO explicitly connects labour standards to the labour dimension of human-rights due diligence [1].

4. What are the five ILO fundamental principles?
Freedom of association and collective bargaining; elimination of forced labour; abolition of child labour; elimination of discrimination; and safe and healthy work [2].

5. Why was safe and healthy work added?
The ILO added a safe and healthy working environment as a fundamental principle in 2022 [2].

6. What is the ETI Base Code?
A nine-clause labour code covering freely chosen employment, association, safety, child labour, living wages, working hours, discrimination, regular employment and humane treatment [3].

7. What are the UNGPs?
The UN Guiding Principles on Business and Human Rights set out the Protect–Respect–Remedy framework and corporate responsibility to respect human rights [8][9][10].

8. What is HRDD?
Human-rights due diligence is the process of identifying, preventing, mitigating, tracking and communicating how human-rights impacts are addressed [1][10].

9. What is modern slavery?
It includes severe exploitation such as forced labour, trafficking, slavery and servitude. The UK guidance discusses these concepts and cites the global forced-labour estimate of 27.6 million people [7].

10. Is the UK Modern Slavery Act a mandatory HRDD law?
No. Section 54 is a transparency duty for qualifying organisations; it is distinct from a mandatory HRDD statute [7].

11. What is responsible recruitment?
Recruitment in which workers are not charged fees, are not deceived, retain documents and are free from coercion.

12. Why do purchasing practices matter?
Because low prices, short lead times and order changes can make excessive overtime, wage pressure or unsafe work more likely.

13. What is worker voice?
The ability of workers to express concerns, individually and collectively, without fear of retaliation.

14. Why is freedom of association important?
It enables collective worker representation and is a fundamental ILO principle [2].

15. What is a grievance mechanism?
A channel through which workers can raise concerns and seek remedy. It must be trusted, accessible and rights-compatible.

16. What is remediation?
Action to put right harm to workers, such as repayment, compensation, reinstatement, medical care or non-repetition measures.

17. Should companies always exit non-compliant suppliers?
No. Exit may sometimes be necessary, but engagement may better protect workers where remedy and improvement are possible.

18. What is risk-based due diligence?
Prioritising the most severe risks to people using scale, scope, irremediability, likelihood and severity.

19. Who should own ethical supply chains?
No single function. HR, procurement, legal, ESG, operations and finance should share governance, with senior accountability.

20. What is good evidence?
Triangulated evidence including policy, process, compliance data, worker voice, grievance data and outcome indicators.

21. Can voluntary standards replace law?
No. Voluntary standards can support practice, but legal duties depend on jurisdiction and entity scope.

22. What should Level 7 students avoid?
Avoid description-only answers. Provide critical analysis, evidence, mechanisms, limitations and justified recommendations.

The level 7 rule

Ethical supply chains are not created by passing audits. They are created by understanding the risks to people, addressing their root causes, listening to affected workers, changing organisational behaviour, and demonstrating that conditions actually improve.
