Legal Question in Employment Law in California

Unless you have a personal employment contract, or are a union member, they can fire you because they don't like the color of your socks if they want to. The only firing that is illegal is if it is for discrimination against you based on a protected classification such as race. That is what at will employment means. HR is never going to make a supervisor work with a subordinate that they don't like working with, no matter how fair. Work isn't about fair, its about the business of the company, and no matter the reason if a supervisor is not happy with an employee that is a conflict that impairs the business of the company.. So unless they fire the supervisor, you are going to go. If they are offering you a severance package, and not claiming you are fired for cause, so you can get unemployment, then take it and find a better job.

In general, unless an employee is civil service, in a union, or has a written employment contract, they are an 'at will' employee that can be disciplined or fired any time for any reason, with or without �cause� or explanation, other than for illegal discrimination, harassment or retaliation under the ADA disability, Civil Rights [age, race, sex, ethnic, religion, pregnancy, etc], Whistle-blower, or similar statutes. The employee's goal should be to keep the employer happy. Unless you fall into one of those protected categories and can prove discrimination, try to negotiate a severance package, and look for new work.
