Pennsylvania workers like you have certain rights and protections under the law that prevent employers from indiscriminately firing you for certain reasons.
Though at-will states allow for an employer to let someone go without having any particular reason to do so, there are some reasons that they still cannot use as an excuse to fire you. For example, it is considered illegal and discriminatory behavior to let someone go strictly because of their race, religion, sexual orientation, gender, and nationality. It is also illegal to discriminate against pregnant women.
Unfortunately, discrimination against these groups still happens every day. This discrimination can come in insidious, sneaky forms that can be hard to notice or fight back against. For example, an employer may try to shift the blame off of themselves by giving you an ultimatum of choosing between being fired or resigning. This is a difficult situation that many vulnerable groups experience. It is a way for an employer to bully you out of your rights and place in the workforce.
Some places may also bully you by making your life at work difficult. They may try to give you only undesirable shifts, cut back your hours, or otherwise make the potential loss associated with quitting the company seem more palatable than the potential gain of staying. They do this to try forcing you into feeling like you must quit on your own.
You don’t have to sit there and take it if you believe that you were wrongfully terminated from your job. Instead, seeking compensation for this termination may help bring you the financial stability that you need in the interim to recover.
