Raising a personal grievance is something you can do when there is a problem in your employment. It’s a formal legal step that tells your employer you have a problem that you want them to fix.
Remember that raising a personal grievance is a formal legal step against your employer. There’s a danger that it might upset them and affect your relationship with them. Before you raise a personal grievance, it might be a good idea to try to talk to your employer about the problem, and give them a chance to fix it before you take it further legally. Whenever you’re dealing with your employer, you should remember that as well as them treating you fairly, you also have to treat them fairly too, and act in ‘good faith’. This means communicating with them properly and trying to deal with any issues before they get worse.
