Legal Question in Employment Law in Pennsylvania

Pennsylvania follows the "employment at will doctrine" which means that you can be fired for "good reason, bad reason, or no reeason at all." Your employer cannot fire you in a way that discriminates based upon protected classes or violates other legal rights, but these restrictions leave your employer with a lot of discretion. They also leave you with a lot of discretion about when to end or continue an employment relationship. The reason, as stated by the employer, is legal.

Fairness is not the question. There are many times that legal rules result in unfair outcomes.

Whether their actual motivation was something that ran afoul of the the other laws, like anti-discrimination laws, would be impossible to know. The good news is that your employer cannot dispute your application for unemployment compensation on the basis of the reason given.
