Legal Question in Employment Law in California

Sure. You can get fired for no reason at all. The only reason you cannot legally be fired is for illegal discrimination, such as race or gender, or for protected conduct, such as union organizing or being a whistle blower to authorities. Otherwise they can fire you any time for any reason or no reason.

There are no laws against 'unfair treatment' or poor management. 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�, explanation or notice, 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 and make the company money. That�s how they pay your wages.
