Maybe. Many workers face discrimination and hostility at work. It may be a good idea to keep a journal or diary of what has happened to you at work. It can be helpful to write down and save information about what people said and did. Just know that if a law suit is filed in your case this journal must be provided to your employer.
A good journal has:
1) Dated entries: each time you sit down to write you include the date, month, and year.
2) Names: individuals are identified by first and last name.
3) Quotes: if you remember exactly what the person has said you include that statements in "quotes."
4) Details: information about location, time of day, the event itself. Detailed description can be helpful in verifying facts and testimony in court.
