It is illegal for an employer to take adverse action against you or harass you if the basis for their conduct is a protected characteristic such as your race, gender, age, or religion. In some states, additional characteristics such as sexual orientation and gender identity are also protected; the extent of available protections for these classes under federal law is not as clear. If your employer’s behavior does not seem to be connected to any of these traits, it may be difficult to find a legal basis for a discrimination or harassment claim. However, many states are enacting workplace bullying laws, which may be more applicable to your situation than anti-discrimination statutes.
