It sounds like employees are telling you certain information, Are they owners or supervisors? I would not rely on the representation of employees about your status. Assuming you were indeed suspended or fired, this is within the rights of an employer if you do not have contractual portection and were hired as an "at will" employee. You may seek unemployment, however, if they punished you for something other people do and do not suffer the same penalty,
Pennsylvania is an at will state in which you can be terminated for a good reason, bad reason, or no reason at all. You cannot be terminated in violation of "Public Policy" which our courts interpret to mean statutes enacted by the U.S. Congress or the Pennsylvania Legislature. When you are terminated because of your "protected classification" (i.e. age, sex, race, national origin, disability, and in some localities gender affinity) it's called "employment discrimination," not wrongful discharge.
In this case, you got into an altercation with a co-worker. Typically, in my experience, altercations between coworkers, regardless of who is right and who is wrong, result in one or both coworkers being fired. It's that simple. The issue of who is telling lies about whom is simply not the employer's problem. If you want to keep your job, steer clear of disputes with coworkers --- period.
Remember, you cannot get legal advice over the internet any more than you should take medical advice from a doctor who has not examined you. This site is designed to point you in the right direction. You have to do the rest. Our dialogue does not create an attorney-client relationship.
