Treat it as a process, not an argument
The moment a complaint arrives in writing, your instinct is usually to explain why the person is wrong. Resist it. A grievance isn't a debate to win, it is a process to follow.
What protects you is fairness and a clear record: that you listened, looked into it properly, and reached a reasonable outcome. An employer who follows a fair process is in a strong position even if the complaint itself has little merit.
Acknowledge the grievance in writing, calmly, and confirm you'll look into it. Don't react defensively.
The basic steps of a fair grievance procedure
Broadly, a fair process means: let the employee set out their complaint, hold a meeting to hear it, investigate where needed, decide on an outcome, and tell them in writing. They have the right to be accompanied at the meeting, and the right to appeal the outcome.
You don't need to be a lawyer to do this well. You need to be fair, consistent, and to keep notes at each step. The ACAS Code of Practice sets the standard tribunals look for, and following its spirit is most of the battle.
Write down the steps before you start, so you handle it in the right order rather than reacting in the moment.
The mistakes that turn a grievance into a claim
The costly errors are nearly always procedural: ignoring the complaint, taking sides before investigating, having the same person who is complained about handle it, or making no record of what happened.
Get the process wrong and even a fair decision can become unsafe. That is what turns a manageable complaint into a tribunal claim, and the real cost is rarely the payout, it is the months of stress and distraction.
Make sure whoever hears the grievance is genuinely impartial, and document every step as you go.
