If you are unhappy about something at work or the way you are being treated a way to tackle this is be writing a grievance to your employer. Guidance may be provided on the drafting of the grievance. Furthermore you may require assistance throughout this process which can be daunting and time-consuming.
Grievance
What is a grievance?
A grievance can be any worry, problem or complaint that you raise with your employer. If a grievance cannot be resolved informally, you should raise it in writing with a manager (if the grievance is about your line manager (for example), the grievance should be raised with another manager). You would need to check whether you have a grievance written procedure in your place of work. If you do then this procedure should be followed.
A failure to raise the grievance in writing does not prevent you from bringing a tribunal claim about the matter. However, you may recover less compensation if you have not done so.
