If a co-worker or supervisor is creating an abusive work environment, it is critical to gather as much evidence as possible to support this claim. Examples of evidence of a hostile work environment include:
Emails;
Texts;
Voice messages;
Handwritten Notes;
Witness statements;
Pictures you take of notes written on a white board, inappropriate pictures or cartoons displayed by a supervisor or co-worker, or any other physical evidence that you cannot safely gather; and
Sudden and unwarranted changes in employment patterns, such as a demotion or unfavorable shift assignment, given without cause.
