• Inside the employment tribunal: The tribunal serves as a specialized court handling workplace disputes from false accusations to breach of confidentiality. Less formal than traditional courts, tribunals provide a focused environment for employment issues. While most hearings conclude within three days, complex cases involving bullying or stress may last longer.

Building your case: Crucial evidence to sue your employer

When facing unfair treatment or mental health discrimination, strong evidence makes the difference. Start collecting proof from day one. Create a detailed work diary recording incidents of bullying, stress, or emotional distress. Save emails, messages, and formal communications, especially those showing breach of confidentiality or false accusations.

• Your essential evidence checklist: Convert your experience of unfair dismissal or employers not paying your salary into solid proof. Keep contracts, payslips, and performance reviews.

• Power of witness support: Colleagues witnessing unfair treatment or workplace bullying can strengthen your case significantly. Their statements about your stress and anxiety at work carry weight in employment tribunal Secure written accounts while events are fresh in memory.
• Expert testimony: Professional opinions matter in work tribunal Medical reports documenting mental health impact, occupational health assessments, and financial expert analysis of unpaid wages bolster your position. These reports help justify employment tribunal costs and validate claims of emotional distress.

Your compensation rights when you sue your employer

The law recognizes both financial losses and personal impact. Emotional distress from unfair dismissal can merit substantial compensation. Mental health deterioration due to workplace bullying or stress often attracts higher awards. Cases involving breach of confidentiality or disclosing personal information may receive additional damages.

• How your award is calculated: The law carefully considers your age and service when calculating compensation for unfair dismissal. If you’re under 22, each year of service adds half a week’s pay. Ages 22-41 receive one week per year, while those over 41 earn 1.5 weeks per year. As of 2024, weekly pay is capped at £643, with maximum basic awards reaching £19,290.
• Financial losses and interest: When facing employers not paying your salary, you’re entitled to more than just backpay. An 8% annual interest applies, plus a potential 50% penalty for wilful non-payment. Breach of contract compensation covers comprehensive losses, from immediate salary to long-term career impacts, including lost benefits, pension contributions, and expected bonuses.
