You my not have any legal options. The fact is that not all employees need to be treated the same or even fairly. Unless some form of actionable discrimination was a factor in your dismissal (i.e. based on your race, religion, etc), no laws have been violated. Your only protection here would be if you have an employment contract, union agreement or company policy to the contrary. Absent that, your employer's actions where lawful.In an at will work environment, an employer has a great deal of discretion in setting the terms and conditions of the workplace. This includes termination for just this type of behavior. In fact, an employee can be fired for any reason or no reason at all.
