If you believe that you have been treated unfairly at work (eg if you feel that you have been bullied or discriminated against), you should consider raising a grievance. A grievance is a formal complaint made by an employee to their employer. You can raise a grievance using a Grievance letter under your employer’s grievance procedure or, if such a procedure doesn’t exist, the Acas Code of Practice on disciplinary and grievance procedures. Your employer should then arrange a meeting to discuss your grievance. If they fail to do so, you can consider taking legal action by, for example, raising a case in an Employment Tribunal. For more information, read Employee grievances and raising grievances.
If you feel that your employer’s conduct has significantly breached your employment contract (eg because of a sudden demotion), you can consider yourself constructively dismissed and can resign using a Constructive dismissal letter. Constructive dismissals cover situations where employees feel that they have no choice but to resign because of their employer’s unreasonable conduct. You may then be able to bring a constructive dismissal claim in an Employment Tribunal. For more information, read Constructive dismissal.
