Making a complaint as a group? Understand the interaction between internal grievances, the Equality Act, and how to manage collective employment tribunal claims effectively.
Collective grievances arise where a group of employees raise a concern or complaint about the same situation at work. In the context of discrimination law in England and Wales, collective grievances can be a powerful way for workers to address systemic issues affecting several individuals rather than pursuing separate individual complaints. Understanding how collective grievances function, how they intersect with discrimination law under the Equality Act 2010, and what practical steps can be taken is key for employees, workplace representatives, and employers. This article explains the legal and procedural context, how collective grievances are managed, interaction with discrimination rights and employment tribunal claims, and practical guidance for effective resolution.
What Is a Collective Grievance?
A collective grievance is a formal complaint raised by two or more employees about a shared issue in the workplace. It might concern terms and conditions, changes in working practices, health and safety problems or allegations of discrimination, bullying or harassment affecting more than one worker. The grievance group may appoint a spokesperson to represent the group in discussions with the employer.
Collective grievances differ from individual grievances in scale and representation. They reflect a common concern among a cohort of employees and can lead to broader workplace consultation or negotiation.⎡
Legal and Procedural Framework
Internal Grievance Procedures
Employers are not legally required to have a written grievance procedure, but most do, and tribunals will view adherence to such procedures as evidence of reasonable conduct. The Acas Code of Practice on Disciplinary and Grievance Procedures sets out minimum fair procedures that should be followed and provides that employment tribunals may adjust awards up or down by up to 25% for unreasonable failure to follow the Code.
However, the Acas Code's specific provisions do not apply to collective grievances raised on behalf of two or more employees by a trade union or other appropriate representative. In these cases, employers should follow their own collective grievance process.
Internal policies commonly state that collective grievances should be raised in writing, outline steps for informal discussion, and then proceed to formal meetings and investigation, with clear timeframes and rights of appeal.
Stage‑by‑Stage Handling
The typical stages of dealing with a collective grievance include:
- Raising the concern: Two or more employees agree on the issue and raise it in writing, often with a spokesperson.
- Informal resolution: Where possible, managers seek informal discussion and resolution before a formal process begins.
- Formal grievance meeting: Representatives of the group meet management to explain the complaint and discuss potential resolutions.
- Investigation: Employers may carry out investigations to understand the facts underlying the collective grievance.
- Outcome and appeal: The employer communicates a written outcome and provides an opportunity for the group to appeal if unsatisfied.
Handling collective grievances fairly and transparently can prevent escalation to formal litigation and help maintain workplace relationships.
Collective Grievances in the Context of Discrimination Law
Discrimination Complaints and Shared Issues
The Equality Act 2010 protects workers from discrimination on the basis of protected characteristics such as age, sex, race, disability, religion or belief, sexual orientation, gender reassignment, marriage and civil partnership, pregnancy and maternity.
Where multiple employees experience the same discriminatory treatment - for example, a workplace policy that adversely affects a group with a shared protected characteristic - a collective grievance allows the group to frame a shared complaint. Issues may include:
- Unequal application of working practices that disproportionately affect a group with a protected characteristic.
- Policies that indirectly discriminate against a category of workers.
- Systemic harassment or biased management conduct affecting multiple complainants.
Addressing these issues collectively can clarify patterns of conduct and ensure consistency in the employer's response.
Interaction With Employment Tribunal Claims
A collective grievance itself is an internal process and does not constitute a tribunal claim. If the grievance does not resolve discrimination concerns, affected employees may decide to pursue employment tribunal claims individually or as a group.
For tribunal action, group claims can be notified to Acas as a ‘group application', allowing early conciliation to be undertaken for all prospective claimants together. Once Acas issues certificates, individuals can lodge claims with the tribunal.
Taking collective grievances seriously and engaging constructively with them can reduce the likelihood of employment tribunal claims or shape negotiations during early conciliation.
Practical Considerations and Challenges
Representation and Spokespersons
Collective grievances are often more effective when employees appoint a spokesperson or representative - for example, a trade union representative or workplace colleague - to help articulate concerns, coordinate evidence, and engage with the employer. This can be especially important where discrimination issues involve detailed factual patterns.
Time Limits and Escalation
While raising an internal collective grievance does not alter statutory time limits for tribunal claims (for discrimination, typically three months less one day from the discriminatory act), it can be a valuable step in documenting complaints and giving the employer an opportunity to resolve issues before tribunal action.
Fairness and Confidentiality
Employers should ensure that collective grievance procedures are conducted fairly and confidentially, respecting individual privacy and data protection obligations while ensuring that the grievance group's concerns are addressed collectively.
Avoiding Retaliation or Victimisation
Employees participating in a collective grievance should not suffer detriment or discrimination because of their involvement. Adverse treatment for raising grievances may itself give rise to claims under the Equality Act 2010 for victimisation.
Examples and Scenarios
Example 1: A group of employees raises a collective grievance alleging that a new flexible working policy disproportionately disadvantages disabled workers who need adjusted hours. The group submits a written collective grievance, the employer investigates, and a resolving session is held to discuss adjustments to the policy.
Example 2: Several employees in a department believe that promotion decisions have been influenced by unconscious bias against a particular ethnic group. They raise a collective grievance together, documented with examples and dates, and request review of the promotion criteria and decisions.
Common Questions
Does a collective grievance replace individual discrimination claims?
No. A collective grievance is an internal process. If the employer's response does not resolve the issue, individuals may still pursue discrimination claims through an employment tribunal.
Does the Acas Code apply to collective grievances?
The Acas Code on disciplinary and grievance procedures does not apply to collective grievances raised by a representative of multiple employees; employers should follow their own procedures.
Can a trade union assist with a collective grievance?
Yes. Trade union representatives can help coordinate and present collective grievances and may also support members in related tribunal claims.
Final Thoughts
Collective grievances provide a mechanism for groups of employees to raise shared concerns, including allegations of discrimination or unfair treatment, with their employer. While internal in nature, collective grievances can play a pivotal role in identifying patterns of conduct, facilitating negotiations, and strengthening the position of individuals who may later choose to bring tribunal claims. Employers and employees should understand how collective grievances fit within broader discrimination law and policy frameworks, ensure procedures are fair and transparent, and consider representation, confidentiality, and statutory rights when engaging in collective processes.
