Legal Question in Employment Law in California

The employer is entitled to set and change hours, duties, titles, compensation, benefits, leaves, vacations, holidays, policies, rules, etc. just not retroactively. Employees have the 'right' to pay and employee benefits per the state wage and hour laws and any formal company policy that may be in place, the right to be provided a 'safe' workplace to minimize risk of injury, and sometimes are entitled by law to certain medical/pregnancy leave rights. That's about it. There no laws against 'unfair treatment' or poor management. The employee's goal should be to keep the employer happy and make the company money. That�s how they pay your wages.
