Understanding How to Raise a Workplace Complaint or Legal Claim Against Your Employer

Many people feel unsure about their rights when problems arise at work. It is common to feel overwhelmed, especially when the employer is a large organisation such as McDonald’s. You may be worried about your job, unsure about the process, or concerned about how your complaint will be handled. Clear guidance helps you understand your position and the steps you can take safely and confidently.

This guide explains how employment law in the UK treats workplace grievances, what options are available if you wish to raise a complaint or take legal action, and how to approach the process in a structured, effective way.


Understanding the issue or context

Workplace problems can take many forms, including unfair treatment, bullying, discrimination, health and safety concerns, unpaid wages or breaches of employment rights. Employees often feel confused about:

  • whether their situation gives them a legal basis to start a claim
  • whether they must raise a grievance first
  • how the grievance process works
  • whether they can take a case to an employment tribunal
  • how to protect themselves during the process

Understanding these points provides clarity before deciding your next steps.


The legal rules or framework

Employment law in the UK offers several protections for workers. The most appropriate route depends on the nature of the problem.

1. A workplace grievance is usually the first step

Employees are encouraged to raise their concerns internally before making a legal claim. ACAS guidance requires employers to follow a fair grievance procedure.

A grievance is suitable for issues such as:

  • bullying or harassment
  • unfair treatment
  • rota or shift problems
  • pay disputes
  • unreasonable management behaviour

2. Some issues may amount to breaches of employment law

If your employer’s actions violate your statutory rights, potential legal claims may include:

  • discrimination (race, gender, disability, age, religion, etc.)
  • harassment
  • victimisation
  • unlawful deductions from wages
  • health and safety breaches
  • breach of contract
  • constructive dismissal

3. ACAS Early Conciliation is required before tribunal claims

If you decide to take legal action, UK law requires you to start with ACAS Early Conciliation. This gives you and your employer an opportunity to resolve the issue before a formal tribunal claim is submitted.

4. Strict tribunal time limits apply

Most employment tribunal claims must be made within three months minus one day of the incident or dismissal. Time limits are very strict.

5. You must have evidence to support your claim

Employment claims rely heavily on documentation, including:

  • emails
  • rotas
  • payslips
  • witness statements
  • grievance correspondence
  • medical evidence (if relevant)

Understanding these rules helps you assess whether you have a potential claim and how to approach the situation.


Practical steps to take (step-by-step guidance)

1. Write down exactly what happened

Record dates, times, people involved and key events. Clear notes help when preparing a grievance or legal claim.

2. Check your employer’s grievance policy

Most organisations, including large employers, have a formal policy explaining how to raise concerns.

3. Submit a written grievance

Set out:

  • what happened
  • why you are unhappy
  • what outcome you are seeking

Keep a copy for your records.

4. Attend the grievance meeting

You have the right to be accompanied by a colleague or trade union representative.

5. Appeal the outcome if necessary

If you are unhappy with the decision, you can appeal. This is part of a fair internal process.

6. Consider ACAS Early Conciliation

If the matter is not resolved internally, contact ACAS. This is free and mandatory before bringing most tribunal claims.

7. Prepare your evidence

Gather all relevant documents. Strong evidence increases the chances of a successful resolution.

8. Seek fixed-fee legal advice

A solicitor can assess:

  • whether your situation meets the legal threshold for a claim
  • what type of claim may apply
  • your chances of success
  • whether the employer’s conduct may breach employment law

This can provide clarity and help you make an informed decision.


Common pitfalls to avoid

  • Delaying action until time limits pass
    Tribunal deadlines are very strict.
  • Relying on verbal complaints
    Always put grievances in writing.
  • Assuming the employer’s process will be fully explained
    It is important to read the grievance policy and ACAS guidance.
  • Not keeping evidence
    The success of any claim often depends on documents.
  • Leaving employment without taking advice
    Leaving too early may weaken certain claims, such as constructive dismissal.
