CAF’s approach to addressing modern slavery
CAF Building Certification involves a process to address modern slavery risk by working with entities at the top of the supply chain to undertake human rights due diligence with regard to procurement, management and delivery of cleaning services; and to engage the entire supply chain in remediation processes where labour rights violations are identified. We focus on the top of the supply chain because procurers of cleaning services have significant power to determine the working conditions of cleaners, despite not being in an employment relationship with them.
The foundations of CAF’s cutting-edge approach to identifying, preventing and mitigating modern slavery risk through certification are:
- the promotion of decent work,
- human rights due diligence,
- recognising the limits of social auditing alone, and
- elevating worker voice.
The promotion of decent work
CAF takes a preventative approach to modern slavery through the promotion of decent work. The International Labour Organisation outlines key components of decent work and decent work opportunities:
- work that is productive
- work that delivers a fair income
- work that is secure
- social protection for the worker and their family
- better prospects for personal development
- freedom to speak up
- freedom of association and to collectively organise
- participation in decision-making
- equality
All of these principles help to prevent modern slavery from occurring and are covered in the CAF 3 Star Standard to varying extents. However given the CAF 3 Star is primarily developed around legal minimum requirements relating to workplace conditions, the principles in bold are of particular focus when it comes to CAF assessments. Other components will have more weighting under the 4 and 5 Star Standard (currently in development).
Decent work is a fundamental component of the UN Sustainable Development Goals (SDGs) most notably regarding SDG 8 (Decent Work and Economic Growth) and SDG 8.7 (end modern slavery by 2025). Furthermore, decent work forms an important part of most of the other SDGs demonstrating its importance in terms of overall development. Stakeholders involved in CAF are having a wider impact in terms of sustainable development than what one might see at a surface level by contributing to broader economic and social development goals.
Human rights due diligence
CAF Certification adopts a ’worker-centric’ due diligence approach – ours is a method that lies within the broader human rights due diligence discourse. We’ll explore this concept more in the section below: ‘Elevating the voice of workers in the supply chain’.
+ What is human rights due diligence (HRDD)?
The Australian Government makes clear in its Modern Slavery Reporting Guidance that business should manage their modern slavery risks using the ‘human rights due diligence’ framework outlined in the United Nations Guiding Principles on Business and Human Rights (UNGPs).
The UNGPs are the current, global authoritative standard on preventing and addressing business-related human rights harms, such as labour exploitation and modern slavery. The UNGPs state that businesses have a ‘responsibility to respect’ human rights of others, which means they should avoid infringing on the human rights of others and address human rights harms with which they are involved. The UNGPs ask businesses meet this responsibility in practice by having a policy commitment to human rights, undertaking ongoing HRDD, and remediating harms with which they are involved.
HRDD is an ongoing risk management process to identify, prevent, mitigate and account for human rights harms arising from a businesses’ activities and relationships, such as their supply chains.
The key steps in the HDRR process1 are:
- risk identification and assessment
- integrating your findings by implementing risk management measures
- tracking and monitoring the measures you have taken
- publicly communicating the action you are taking (for example in your modern slavery statement).2
+ HRDD and CAF Certification
The CAF Certification process addresses modern slavery risks by facilitating ongoing human rights due diligence in relation to labour rights violations in a building’s cleaning services from the point of procurement and throughout the life of the contract, using a worker-centric approach.
HRDD and risk
This section will be of assistance to those responding to modern slavery reporting Criterion 4, which asks entities to describe the steps they have taken to assess and address their modern slavery risks, including due diligence and remediation. The Government’s Modern Slavery Reporting Guidance explains that the reference to ‘due diligence’ in criterion 4 is a reference to ‘human rights due diligence.
CAF Certification facilitates identification, assessment, management and remediation of modern slavery and other labour exploitation risks. CAF Certification address the following risk areas that are systemic in the cleaning industry:
- opaque and insufficiently priced cleaning contracts,
- widespread underpayment of wages and entitlements,
- unsafe workloads and working conditions, and
- lack of worker voice.
We do this by:
- educating stakeholders on the various factors that increase modern slavery risk,
- awareness raising of past and present labour rights abuse of cleaners in a business’ operations and supply chains, and
- providing guidance on how to prevent reoccurrence of non-compliance with labour standards
Risk identification and assessment
CAF Certification involves an independent third-party assessment of modern slavery supply chain risk including procurement processes, employment practices, oversight of contractor compliance, and supply chain transparency and accountability.
CAF’s assessment of labour standards at a building also focuses on risk to people by identifying dangerous or substandard working conditions which can be indicators of modern slavery, and a process to diagnose the presence of slavery-like practices primarily through worker engagement.
The CAF modern slavery diagnostic process includes questions to workers about recruitment fees and debts, deceptive recruitment, coercive practices, and threats of deportation. Through the holistic education and engagement CAF conducts with workers in conjunction with United Workers Union, we are also able to determine if workers appear to be being controlled and fearful about speaking up, which can be a warning sign that workers are being subjected to slavery-like practices.
The UNGPs stress the importance of centring the voices of potentially affected stakeholders (such as workers) in the process of identifying and assessing human rights risks, and consulting stakeholders directly to understand their concerns, in a manner that takes into account language and other potential barriers.3 The CAF modern slavery diagnostic process includes questions to workers about recruitment fees and debts, deceptive recruitment, coercive practices, and threats of deportation. Through the holistic education and engagement CAF conducts with workers in conjunction with United Workers Union, we are also able to determine if workers appear to be being controlled and fearful about speaking up, which can be a warning sign that workers are being subjected to slavery-like practices.
Through the CAF Certification process, stakeholders are required to demonstrate compliance with the CAF 3 Star Standard. Where non-compliance is identified, stakeholders must implement corrective action to achieve and maintain certification.
Risk management and remediation
At the time of tender, property owners and managers involved in CAF manage their risk by including CAF requirements in their cleaning tenders and contracts, setting the expectation and contractual obligation for their cleaning service providers to meet the CAF Standard as part of their engagement, and participate in a CAF Building Certification assessment during the lifetime of the contract.
Once the contract is in place, stakeholders:
- are educated on the various factors that increase modern slavery risk,
- are made aware of past and present labour rights abuse of cleaners in their operations and supply chains, and
- receive guidance on how to prevent reoccurrence of non-compliance with labour standards
Property companies continue to manage risks through ongoing compliance checks in their certified buildings, which involves requesting evidence of compliance at regular intervals; conducting unscheduled spot checks of their cleaning service providers; engaging directly with cleaners at their buildings through CAF worker engagement meetings and quarterly meetings with the CAF Representative; participating in CAF Annual Health Checks, where ongoing compliance is assessed; investigating and remediating (either directly or requiring remediation by their suppliers) of contraventions of labour standards.
Given the serious and systemic nature of exploitation in the cleaning industry, it is near certain that there will be a labour rights violation in a cleaning supply chain. An important part of risk management and remediation is to encourage the timely reporting of issues and supporting the remediation of any violations. It is also important not to set a target of 100% compliance as we know this is near impossible to achieve and will only discourage your supply chain from speaking up about issues.
Examples of remediation implemented through CAF certification include repayment of unpaid wages and entitlements, proactive measures relating to workplace health and safety, bullying and harassment, discrimination, training, working time, freedom of association, worker education, supervisor training, and revision of cleaning contractor policies and procedures.
+ HRDD – ongoing effectiveness of action
This section will be of assistance in responding to modern slavery reporting criterion 5 which asks entities to describe how they assess the effectiveness of actions taken.
The UNGPs expect that businesses will track the effectiveness of their responses to human rights risks to drive continuous improvement, using qualitative and quantitative indicators, and drawing on feedback from both internal and external sources, including affected stakeholders (e.g. workers).4 The CAF Certification process assists stakeholders track the effectiveness of the actions to manage labour rights and modern slavery risks and to obtain regular feedback from vulnerable workers about the effectiveness of these actions.
As part of CAF Building Certification, owners, building managers, and cleaning contractors involved in the process receive detailed third-party reporting on compliance with the CAF 3 Star Standard. This includes two key reports: the supply chain assessment report and the worker engagement report. Reporting includes findings based on assessable components of the CAF 3 Star Standard, observations and requirements to implement to achieve certification. On a deeper level, stakeholders involved in a building certification also receive feedback from cleaners at the site, compiled by CAF based on feedback from cleaners obtained through a survey, worker engagement meetings, and any additional follow-up communication by cleaners to their union and CAF. The worker engagement report contains recommendations for investigation and remediation as appropriate.
Stakeholders in building certification also receive feedback from cleaners at the site, compiled by CAF based on feedback from cleaners obtained through a survey, worker engagement meetings, and any additional follow-up communication by cleaners to their union and CAF. The worker engagement report contains recommendations for investigation and remediation as appropriate.
When certification is obtained, the building manager is given a toolkit for ongoing compliance, which details a schedule and guidance for regular checks to take place between supply chain stakeholders at the building. In addition, CAF will conduct an annual health check to assess the effectiveness of ongoing compliance monitoring and enforcement over the preceding 12 months. This and the reporting form the basis of monitoring and tracking the ongoing effectiveness of certification.
Ongoing compliance focuses heavily on cleaner consultation through annual repetition of the CAF worker engagement process – meetings with cleaners, CAF survey of cleaners, investigation and remediation of any issues raised by cleaners. In addition, the CAF Representative will conduct assessment of compliance providing reporting entities with regular direct worker feedback on any issues that could indicate a risk of worker exploitation or modern slavery.
Key to this ongoing compliance monitoring process is the continuous elevation of worker voices, discussed in more detail below.
A CAF Representatives5 is a cleaner that has been selected by their peers, the union and CAF on the basis that they best represent workers’ interests. The CAF Representative cannot be a supervisor or manager or in another position of authority. The CAF Representative receives training, support and an allowance to carry out tasks designed to ensure ongoing compliance with the CAF Standard. CAF Representatives play a key role in effective and ongoing compliancehere as they educate fellow workers on the CAF Standard and how to raise issues; liaise regularly with their employer and the lead entity (i.e. building owner/manager) on ongoing CAF compliance; and consult with the union, CAF and other CAF Representatives to continuously develop their leadership and monitoring skills.

Recognising the limits of social auditing
Social auditing generally refers to the process an entity will go through either in relation to its own operations or those of its suppliers to verify compliance with human rights standards. These standards might relate to well-established global standards such as the UN Guiding Principles on Business and Human Rights, specific standards such as the CAF 3 Star Standard, or will be outlined in an entity’s code of conduct or ethical sourcing policy.
Typically, a social audit will involve interviews and surveys with management and employees; assessment of any entity policies, procedures and statements related to labour and human rights; and employee-related document audits (i.e. time and wages check, employment contract check etc.) and in some cases, physical workplace inspections.
While social audits play a role in human rights due diligence, they are designed to be one tool in a broader suite of processes to encourage lead firm and supplier compliance with labour and human rights standards.
+ View an outline of limitations to social audits
- Audits are widely recognised as ineffective tools for detecting and remediating labour violations in supply chains (e.g. Rana Plaza factory building collapse in 2013 that killed over 1000 workers and was given a clean audit report days before)
- Audits can be subject to manipulation and deception (e.g. Fair Work Ombudsman Inquiry into 7-Eleven)
- Potential for conflicts of interest with the entity commissioning the audit and the auditor
- Audits are a point-in-time snapshot and tend to take on a short checklist quality
- Social auditors often do not have real-life experience in the field in which they are auditing (e.g. auditors that have not been a cleaner themselves/interacted with cleaners or their representatives on a regular basis will not fully understand the context/intricacies of when and how issues arise, meaning things can slip through the cracks).
- Workers involved in social audits are often vulnerable workers reluctant to speak up due to a well-founded fear of retribution.
- Social audits are often focused on the supplier which can identify symptoms of labour exploitation (i.e. wage underpayment) but does not address the root cause (i.e. poor procurement practices). This then becomes a band-aid solution and continues to put workers at risk of exploitation and modern slavery.
- On worker voice tools: “The kind of “worker voice” tools that are designed to complement social auditing – instead of challenging the status quo – are structurally unable to fulfill their promise of empowering workers to improve their own labor conditions, because they do not provide workers with protected and collective mechanisms through which they can demand respect for their rights and improvements to their wages and conditions of work without fear of reprisal.”
In consideration of the above, business and human rights experts argue that “The current model of social auditing promotes a coercive culture that encourages cheating and corruption and reinforces underlying power asymmetries. Workers, unions, NGOs and other stakeholders who might counteract these issues and shed light on violations tend not to be meaningfully involved in the process.”

CAF’s approach: Elevating the voice of workers in supply chains
CAF takes a more holistic approach by combining social audits, meaningful worker engagement, and education and training for the whole supply chain. CAF Certification involves a process to promote good labour practices, correct poor labour practices, and to educate and support workers to identify and raise labour rights violations. Our model is based on worker-driven social responsibility (WSR) which is a relatively new concept but one that is fast gaining traction globally as best-practice human rights due diligence. Engaging workers is critical to managing modern slavery risk in your supply chain as they are your eyes and ears on the ground.
CAF’s worker centric approach reflects key recommendations from the Government’s Modern Slavery Guidance (p.52) regarding action to assess and address modern slavery risks including:
- engag(ing) directly with workers in your operations and supply chains, as well as credible experts, to assess risks.
- sett(ing) up a mechanism to allow people to safely report modern slavery risks in your entity’s operations and supply chains
Key aspects of CAF’s worker-centric approach
+ Responsible supply chain standards
The CAF 3 Star Standard has been developed in consultation with business, government, academics and most importantly, workers. This is important as some ethical sourcing policies and codes of conduct are drafted with no-minimal input from workers therefore weakening any positive impacts on workers as a result of social audits that are conducted on these frameworks.
+ Top of supply chain responsibility
CAF certification is driven by the top of the supply chain thereby addressing the root causes of exploitation and modern slavery. Engaging CAF as an independent third party disrupts the traditional power dynamic in the supply chain where we, together with the union, can talk to workers without them having a direct threat of dismissal or punishment. We also require the top of the supply chain to take more responsibility for conduct throughout the supply chain which is typically outsourced to the supplier and can be covered up.
+ Whole of supply chain assessment
While there are inherent flaws with audits, they are still useful tools at uncovering compliance issues within a supply chain. Most audits focus on the business practices of suppliers, to the exclusion of those of the procurer. CAF has screened and trained auditors to undertake robust supply chain audits that focus on known problem areas within the cleaning industry, including the employment practices of the cleaning company, but also the procurement and management process. We have also developed our own unique audit methodology in consultation with independent auditors, compliance officers from the Fair Work Ombudsman and industrial officers from the United Workers Union.
+ Worker participation, capacity building, and representation
Our unique Worker Engagement method is focused on worker participation rather than worker interviews. We combine one-on-one interactions and group interactions (both in person and online) to obtain accurate information and to build confidence and capacity within the target workforce to monitor and enforce their labour rights. Our approach recognises that building trust with vulnerable workers takes time but that doing so will enable them to speak more freely about workplace issues. In addition, we require and equip other supply chain participants such as building managers to also build trust with workers, creating an even more transparent and safe environment for vulnerable workers. CAF worker engagement brings workers together to talk about conditions. Building community amongst the workforce is essential to mitigating the risk of modern slavery and exploitation – vulnerable workers will be more likely to speak up if they feel supported by a collective, rather than raising a concern as an individual, out of a well-founded fear that they will be dismissed from their job or moved off-site.
CAF works with the union representing property services workers, United Workers Union, when directly engaging with workers and other stakeholders involved in CAF Certification. This adds credibility to the certification scheme as the union officials involved are often former property services workers themselves, have expert insight into the industry and worker conditions, and the union provides a structure for workers to stand together and advocate collectively. CAF’s worker engagement assessments are conducted with union officials, ensuring that workers have a genuine role in the assessment.
+ Ongoing compliance
CAF Certification requires ongoing compliance with the CAF 3 Star Standard from all entities within the supply chain at certified buildings, not just at the point of certification. Ongoing compliance is achieved through a program of regular monitoring of labour standards, capacity building of stakeholders at certified buildings, and by continuous worker education and empowerment (cleaners supported by their union).
