How to write a complaint about a manager

How to describe a manager’s conduct factually, keep the focus on specific events, and ask for a clear next step.
Complaints that stick to specific events are easier to understand and act on. This guide is general information, not legal advice. Deadlines and rules differ, and using Report 2 HR does not stop or extend any deadline. See Official help for agencies.

Focus on specific events

Write what the manager did or said, with dates and places, instead of general opinions. “On June 4 he removed me from the schedule without notice” is clearer than “he is unfair”.

Show the effect

If the conduct changed your hours, pay, duties or health, say how, and when it changed.

Mention earlier attempts

If you already raised the issue with the manager or someone else, say when and what happened.

Be calm and specific

A report in a steady tone, with facts you can support, is easier to take seriously. You do not need legal words.

Ask for a next step

Say what you hope will happen: a meeting, a change to scheduling, a written reply. Then keep a copy.
Fictional sample: schedule changes after raising a concern
This sample is fictional. Names and events are made up.
On May 6 I told my manager, Jordan Sample, that I had not been given my meal break for two days. On May 9 my schedule for the next week was changed from five days to two without notice.
On May 12 Jordan told me, “If you want hours, stop complaining.” No one else was present. I wrote this down the same day.
I am asking for my scheduled hours to be restored and for a written reply.
