The 2 week notice?

“I Just Gave My Employer Two Weeks’ Notice and the Employer Fired Me. What Can I Do?”

Pennsylvania is an 'AT WILL ’ state. An employer does not need to give a reason to fire an employee under Pennsylvania wage and hour laws. However, you may wish to check with an attorney to see whether or not you can file a civil lawsuit against your employer for wrongful discharge. Also, if you feel you were discriminated against because of race, creed, color, age, religion, sex, or similar reason, you may wish to contact the Pennsylvania Human Relations Commission at 1-717-787-4410.
