Retaliation Evidence Guide
How to spot and preserve proof that an employer punished you for protected activity.
What counts as protected activity
Protected activity can include complaining about discrimination or harassment, requesting a disability or religious accommodation, reporting wage theft, raising safety or legal violations, or participating in an investigation. The complaint does not have to be proven correct if it was made in good faith under the applicable statute.
Adverse actions to document
Termination is the clearest hit, but demotion, cut hours, write-ups, transfer to a worse shift, exclusion from projects, or sudden negative reviews after years of praise can also qualify. Note the date of your protected activity and the date each adverse action began.
Evidence that often helps
Emails or texts acknowledging your complaint; HR tickets; witness names; before-and-after performance scores; schedules showing hour cuts; and comments suggesting you were a “troublemaker” for speaking up. Close timing between the complaint and the punishment is frequently powerful—though not required in every theory.
