How to Report Discrimination to Employer

Reporting discrimination to an employer is the first formal step in addressing unlawful treatment at work based on a protected characteristic. It forms part of the internal resolution process expected under UK employment practice and is often relevant in later Employment Tribunal claims under the Equality Act 2010.

Workplace discrimination reports can relate to direct discrimination, harassment, victimisation, or failure to make reasonable adjustments. Employers are expected to take such complaints seriously, investigate them promptly, and respond in line with fair procedures.

This guide explains how to report discrimination to an employer, what information to include, how employers should respond, and how the process links to tribunal claims and ACAS Early Conciliation.

What Workplace Discrimination Means in Law

Workplace discrimination is governed by the Equality Act 2010.

It protects individuals with the following characteristics:

• Age
• Disability
• Sex
• Race
• Religion or belief
• Sexual orientation
• Gender reassignment
• Pregnancy and maternity
• Marriage and civil partnership

Discrimination can take several forms:

• Direct discrimination (less favourable treatment because of a protected characteristic)
• Indirect discrimination (policies that disadvantage a protected group)
• Harassment (unwanted conduct linked to a protected characteristic)
• Victimisation (detriment for raising a complaint or supporting another person)

Understanding the category of discrimination helps ensure the complaint is framed correctly when reporting it to an employer.

Why Reporting Discrimination to an Employer Matters

Reporting discrimination internally serves several practical and legal functions:

• It alerts the employer to potentially unlawful conduct
• It triggers internal investigation procedures
• It creates a written record of concerns
• It may resolve issues without formal litigation
• It supports later Employment Tribunal evidence if the issue escalates

Employment tribunals often consider how an employer handled complaints when assessing fairness and liability.

Step 1: Decide Whether to Report Informally or Formally

There are usually two routes:

Informal reporting

This may involve:

• Speaking to a line manager
• Raising concerns directly with the person involved
• Requesting informal resolution or mediation

Informal reporting is typically used for less serious or early-stage issues.

Formal reporting

A formal complaint is appropriate where:

• The conduct is serious (for example harassment or repeated discrimination)
• Informal steps have failed
• The issue involves senior staff or HR
• There is ongoing or escalating behaviour

If the issue may involve legal claims, formal reporting is usually more appropriate.

Step 2: Follow the Employer's Policy or Grievance Procedure

Most employers must have a written grievance process. This sets out:

• Who to report to
• How complaints should be submitted
• Investigation steps
• Timelines
• Appeal procedures

The formal complaint process is often referred to as a grievance.

ACAS guidance confirms that employers should handle discrimination complaints using fair procedures consistent with the ACAS Code of Practice on disciplinary and grievance procedures.

Failure to follow fair procedures can later affect tribunal outcomes and compensation levels.

Step 3: Write the Discrimination Report Clearly and Factually

A written complaint is usually the most effective method of reporting discrimination.

A strong report should include:

1. Basic details

• Your name and job role
• Department and workplace location
• Names of individuals involved

2. Chronology of events

• Dates and times of incidents
• What happened in each incident
• Who was present

3. Description of discriminatory behaviour

• What was said or done
• Why it is believed to be discriminatory
• Any repeated patterns

4. Protected characteristic link

• Which protected characteristic is relevant
• How the treatment relates to that characteristic

5. Impact

• Emotional impact (stress, anxiety, distress)
• Workplace impact (performance, absence, resignation risk)
• Financial impact (if applicable)

6. Supporting evidence

• Emails or messages
• Witness names
• Documents or policies

ACAS guidance recommends including both a clear description of events and specific questions for the employer to investigate.

Step 4: Submit the Report to the Correct Person

The complaint should be sent to:

• HR department
• Line manager (if appropriate)
• Senior manager not involved in the complaint

If the complaint involves the line manager, it should be escalated to HR or a higher authority.

It is important to keep a copy of the report and proof of submission.

Step 5: Employer's Duty to Investigate

Once a discrimination report is made, the employer is expected to:

• Acknowledge the complaint
• Conduct a reasonable investigation
• Interview relevant parties
• Review documents and evidence
• Provide a written outcome

The investigation should be impartial and timely.

Where employers fail to investigate properly, this may be relevant in any subsequent tribunal proceedings.

Step 6: Possible Outcomes of Reporting Discrimination

After investigation, the employer may:

• Uphold the complaint fully or partially
• Reject the complaint
• Recommend disciplinary action against others
• Introduce workplace changes or training
• Offer mediation or settlement discussions

In some cases, the complaint may lead to a formal grievance hearing.

Step 7: If the Employer Does Not Act Properly

If the employer:

• Ignores the complaint
• Delays unreasonably
• Fails to investigate
• Retaliates against the employee

this may itself amount to victimisation under the Equality Act 2010.

At that stage, escalation options may include:

• Formal grievance escalation or appeal
• Contacting ACAS
• Starting Early Conciliation
• Preparing an Employment Tribunal claim

Step 8: Link to Employment Tribunal Claims

Reporting discrimination internally is not always legally required before a tribunal claim, but it is often relevant to:

• Evidence of discrimination
• Employer awareness of issues
• Reasonableness of conduct
• Compensation assessments

Tribunal claims for discrimination must usually be brought within three months less one day of the discriminatory act, subject to ACAS Early Conciliation pausing limitation periods.

Common Mistakes When Reporting Discrimination

• Being too vague or general
• Failing to include dates or specific incidents
• Not linking behaviour to a protected characteristic
• Delaying reporting until too late
• Not keeping copies of evidence
• Using emotional language instead of factual detail

Clear structure improves the effectiveness of the complaint and strengthens any later legal process.

Practical Considerations

• Keep a written timeline of incidents
• Preserve all communications and documents
• Follow internal procedures precisely
• Use factual, neutral wording
• Be aware of strict tribunal time limits
• Consider ACAS Early Conciliation if the issue is not resolved

Key Takeaways

Reporting discrimination to an employer involves making a clear, factual complaint through internal procedures, usually supported by written evidence and linked to a protected characteristic under the Equality Act 2010. Employers are expected to investigate and respond fairly, following the ACAS Code of Practice.

If internal resolution fails, the issue may escalate to ACAS Early Conciliation and potentially an Employment Tribunal claim. The way the complaint is reported and handled can significantly influence later legal outcomes.
