What should I do in regards to a hostile work environment?

A "hostile work environment" is a workplace environment that prevents you from doing your job duties in a reasonable manner. In such an environment a superior or co-worker, either by behavior or actions, creates an environment that is counterproductive to your performingyour work duties. However, these behaviors typically must be "discriminatory" in nature and are not just a result of rude or unprofessional behavior. And discrimination in a workplace setting means action taken against you because you are a member of a "protected class"; in other words based on your race, religion, age, disability, sexual orientation, gender, national origin, etc.

Based on what you write, you should contact either the federal Equal Employment Opportunity Commission (EEOC) or your state's labor department. You may also wish to consult with an employment attorney (the initial consultation is often free; ask about this before making an appointment) to see if you do have an actionable claim.
