I was fired for one reason and then found out later that it was for another. Do I have a case?

An employee without a union or employment contract is an employee at will and can be fired for no cause at all. Unless race, gender, age, religion etc... is the basis for your firing, you have no recourse.

You might consider working at a place that allows you to be who you are. Only you know the environment there at the job.

Good luck to you.
