Grievance Mechanisms
This section shows whether one or more grievance mechanisms have been identified as present at this production location through integrations with Spotlight Partners. A grievance mechanism is a formal channel through which workers can raise concerns, complaints, or reports of rights violations.
OS Hub does not operate these mechanisms or receive grievance submissions. The platform surfaces information provided by partner organizations to improve visibility into grievance channels that may be available at a production location.
The absence of a grievance mechanism in OS Hub’s data for a production location does not mean that no mechanism exists there. State-based systems, workplace-level channels, or locally operated mechanisms may be available but may not be reflected in our data.
We recognize that grievance infrastructure is broader than what is currently captured in OS Hub’s data. Governments, worker organizations, civil society groups, industry initiatives, and other actors that operate or oversee grievance mechanisms are encouraged to share information to help improve the completeness and accuracy of this data.
Grievance mechanisms shown here may include:
Brand/ Buyer Operated Grievance Mechanisms
Grievance mechanisms established by brands/buyers to receive and address complaints related to working conditions within their supply chains.Supplier/Facility Operated Grievance Mechanisms
Grievance mechanisms established and operated by suppliers or production facilities that allow workers to raise complaints within a specific workplace. These mechanisms function at the production location level and may include internal workplace complaint channels as well as mechanisms established to comply with legal requirements. They are distinct from external state-administered labor complaint or dispute resolution systemsSectoral or Multi-Stakeholder Operated Grievance Mechanisms
Grievance mechanisms established and governed through sectoral platforms or multi-stakeholder initiatives involving brands, suppliers, worker representatives, and civil society organizations. These mechanisms generally operate through shared or joint oversight structures and are designed to receive and address complaints related to working conditions across supply chains.Trade Union Operated Grievance Mechanisms
Grievance channels operated by trade unions that receive complaints from workers and support them in pursuing resolution or remedy.Third-Party or Independently Operated Mechanisms
Grievance mechanisms operated or administered by independent organizations or service providers that play a direct role in receiving, managing, or processing grievances.
These systems may be commissioned or funded by brands, suppliers, or other actors, but are not controlled by the commissioning entity, and the third party has a substantive role in how grievances are handled.
They are distinct from digital tools or platforms used by facilities or brands where decision-making and grievance outcomes remain internal to the facilities or brand.
For example, a factory may use a digital tool to collect worker complaints, but if the factory management retains control over how grievances are assessed, addressed, and resolved, it would still be classified as a facility-operated mechanism, not a third-party mechanism.
Where did this data come from?
OS Hub aggregates information shared by Spotlight Partners about grievance mechanisms linked to production locations. Where available, OS Hub also provides links to partner platforms that offer additional details about these systems.
The presence of a grievance mechanism on a production location profile indicates that a partner organization has reported the mechanism as active at, or associated with, that location. This information helps increase visibility into grievance channels that may be available to workers in that location.
OS Hub surfaces partner-reported information but does not independently verify the operation, accessibility, or effectiveness of individual mechanisms. As a result, the presence of a grievance mechanism on a production location profile does not necessarily indicate that:
- The mechanism is actively used by workers
- Workers are aware of or able to access the mechanism
- Grievances raised through the mechanism have been resolved
Information about grievance mechanisms may also change over time. While OS Hub makes best efforts to keep this information up to date, the platform relies on partner organizations and mechanism providers to share updates. Listings may therefore not always reflect the most recent operational status of a mechanism.
How can you use this data?
There are many ways you might analyze or factor this information into your programs.
The grievance mechanism information displayed on production location profiles provides visibility into mechanisms that may be linked to a production site. It should be used as a starting point for understanding the grievance infrastructure that may exist around that location.
IMPORTANT: This information should be used responsibly and not in ways that could expose workers to retaliation or undermine their ability to safely raise concerns. If you are unsure, contact us, we are happy to provide guidance.
Users can use this information to:
- Map grievance infrastructure across supply chains
Identify which facilities are linked to grievance mechanisms and understand what types of mechanisms are present across different regions, sectors, or tiers of a supply chain. - Identify potential gaps in grievance coverage
Where no mechanisms are currently reflected, users may wish to follow up with those facilities and relevant local stakeholders to determine whether mechanisms exist but are not captured here, or whether gaps in grievance infrastructure may be present. - Access additional information through partner platforms
Where links are provided, users may visit partner platforms for further information about the design, scope, or operation of a specific grievance mechanism. - Engage with worker representatives and local stakeholders
Understanding whether workers are aware of, trust, and are able to safely use grievance mechanisms often requires engagement with workers or their representatives. Where trade union contacts are listed for a region, users may reach out to these organizations to better understand local grievance channels and worker experiences. - Contribute additional information
Production location owners, grievance mechanism operators, civil society organizations, trade unions, and other relevant actors that operate, manage, or are aware of additional grievance mechanisms linked to a location, are encouraged to share this information to help improve the completeness of the data.
What you should not do with this information
Do not assume that the presence of a grievance mechanism means it is accessible, trusted, or effective for workers.
Do not treat grievance mechanisms operated by brands, suppliers, third parties, or other actors as a substitute for state-based or legally mandated complaint systems. State systems often carry legal enforceability and play an important role in access to remedy.
Do not interpret the absence of grievance mechanism information on a production location profile as confirmation that no grievance mechanism exists. Other mechanisms may exist but may not yet be reflected in our data.
Do not rely on this section as a substitute for direct engagement with workers, trade unions, suppliers, or other stakeholders. Understanding how grievance mechanisms function in practice often requires engagement with workers and their representatives.

Accord/RSC Grievance Mechanism
The International Accord provides facility-level data on Bangladesh garment factories under the Bangladesh Safety Agreement, implemented by the RMG Sustainability Council (RSC). The data includes each factory’s initial inspection date and coverage status, allowing users to identify which facilities participate in fire, electrical, structural, and boiler safety inspections and remediation. Additionally, the data shows where workers have access to an independent complaints mechanism to raise health and safety concerns.
Data points
- Status: If set to Active, indicates that this is a factory covered by the Accord/RMG Sustainability Council (RSC), therefore, the grievance mechanism is accessible to all workers in the factory.
- Thematic coverage: Indicates the scope of issues that workers can raise through the mechanism.
- Mechanism type/ownership: Captures who owns, operates, and ultimately controls the grievance mechanism, including its governance and decision-making structure.
- Access/modality: Indicates how workers can access and engage with the grievance mechanism in practice.
- Coverage: Indicates who can access the grievance mechanism and the level at which it operates.
Methodology
All Accord signatories disclose their sourcing facilities in Bangladesh, and the Accord maintains and publishes this supplier list. Once a facility is listed by a signatory, an independent Complaints Mechanism becomes available to all workers and their representatives at the facility. Since June 1, 2020, this Complaints Mechanism in Bangladesh has been operated by the RMG Sustainability Council (RSC). For more information, visit our website.
Coverage
Includes all Cut-Make-Trim (CMT) ready-made garment facilities in Bangladesh producing for and listed by Accord signatories, plus voluntarily disclosed home textile and accessory suppliers.
Update frequency
Updated quarterly.
How others use this data
Organizations use this data to assess whether workers have access to effective remedy at a particular facility, enabling them to safely raise health and safety concerns.
Under the Accord’s Complaints Mechanism, implemented by the RMG Sustainability Council (RSC) in Bangladesh, workers in all covered factories have access to a confidential, independent complaints process, ensuring they can report health and safety concerns without fear of retaliation. The RSC independently investigates complaints and works with factory management to implement appropriate remedies. This enables brands, unions, NGOs, and monitoring bodies to evaluate and strengthen factory-level health and safety compliance within garment supply chains in Bangladesh.

Ulula Grievance Mechanism
Ulula provides facility-level data regarding the availability and initiation dates of grievance mechanisms across 62 countries. This enables buyers to quickly identify production sites with active worker voice programs, review adoption history, and increase supply network transparency via the Open Supply Hub.
Data points
- Status: Whether the Ulula mechanism is currently active at this facility.
- Active since: The date the Ulula mechanism was first deployed at this facility.
- Thematic coverage: Indicates the scope of issues that workers can raise through the mechanism.
- Mechanism type/ownership: Captures who owns, operates, and ultimately controls the grievance mechanism, including its governance and decision-making structure.
- Access/modality: Indicates how workers can access and engage with the grievance mechanism in practice.
- Coverage: Indicates who can access the grievance mechanism and the level at which it operates.
Methodology
Grievances are submitted anonymously through multiple channels, including mobile, web, and phone calls. These are received by either the supplier or an independent case manager, depending on the project. Our system facilitates two-way anonymous communication, allowing case managers to track steps from submission to resolution while keeping all parties informed. Key features include case tracking, automated notifications, and escalation pathways for high-sensitivity or "zero-tolerance" cases that require urgent attention.
The mechanism is overseen by worker engagement specialists and human rights experts who review grievance protocols, cases, and Service Level Agreements (SLAs). Suppliers can monitor resolution progress through aggregated statistics at both macro and micro levels.
Here’s how it works:
- Ulula and our worker engagement specialists manage on-the-ground training and oversight.
- Brands influence and sponsor implementation, review progress, and act as escalation points for high-risk cases.
- Suppliers serve as the primary point of contact, reviewing and remediating grievances.
- Third Parties run and promote the system as responders and managers within specific sector initiatives.

Grievance Mechanisms FAQs
In some cases, summary information is displayed directly on OS Hub. For the full dataset — including individual mechanism details, coverage, and outcomes where available — follow the links to the relevant partner platform. The amount of data visible on OS Hub varies by partner, depending on data sensitivity, ownership structure, and business model.
These two sections reflect different types of connections to OS Hub. The Spotlight Data section shows data from Spotlight Partners who share custom data with OS Hub through a dedicated agreement. The Supply Chain Network section shows organizations that contribute data to OS Hub through the standard upload process. An organization can appear in one or both sections depending on how they are connected to OS Hub.
No. This section is for supply chain stakeholders to see what mechanisms exist at a production location. It is not a submission portal for workers. If you are a worker seeking to raise a concern, please contact the relevant mechanism directly or reach out to your national labor authority.
A production location may have more than one grievance mechanism in place — this is not unusual and can reflect different channels serving different purposes. For example, a facility may have both a brand-operated mechanism and an independently operated third-party channel active at the same time. Multiple mechanisms may also reflect different OS Hub partners each identifying a separate active channel at the same location.
The presence of multiple mechanisms does not necessarily mean they are complementary or that workers are aware of all of them. We recommend reviewing each mechanism individually and engaging directly with the production location to understand how grievance channels are communicated to and used by workers in practice.
The UN Guiding Principles on Business and Human Rights (UNGPs) provide an important and widely recognized framework, including a high-level distinction between state-based and non-state-based grievance mechanisms, and a focus on operational-level mechanisms.
For the purposes of OS Hub, this categorization is sometimes too broad to clearly reflect how different mechanisms are structured and operated in practice. For example, mechanisms with very different governance models, scopes, or modes of operation may fall within the same UNGP category.
In addition, UNGP terminology can be technical for general users, particularly workers and grassroots organizations seeking to understand who operates a mechanism and how it functions.
To support clearer understanding, OS Hub uses more descriptive categories—such as employer/facility-operated, brand-led, third-party, or trade union-led—which aim to provide accessible, practical information about how a mechanism is organized and who is responsible for it. These categories are intended to complement, rather than replace, the UNGP framework.
