Pizza Hut

I am a former employee of pizza hut in elizabeth city. I was the primary cook, & I use the term lightly as we were (& still are) extremely understaffed. As such, I was responsible for ALL make table, cut table & wing street duties. I will not say the management wouldn't help out, but I was the driving force in this store. We are located in a small town, which makes us the only buffet in town besides the chinese restaurant. I would perform these duties after working a 8 hour shift overnight at another place of employment 5 days a week. As a result, I would see only 2 hours of sleep per day mostly. The reason for my complaint is because I was recenty fired. I got into a rather loud & obscene arguement with a server because of her lack of professionalism & respect toward the kitchen staff. I'm not making excuses. We were both loud. We were both using profanity. I will say I remained in the kitchen area while her loud comments were made from the front line. My fellow employees heard her in the dish room. I could hear her from inside the dough cooler. When I went into the dishroom to confront her, her pushed the rolling server tray full of dishes at me & I pushed it back in retaliation. As I was immediately fired, she was not. The issue is that this manager is sleeping with this server & because of this, his judgement is greatly clouded. It is public knowledge throughout the staff that they are involved in an affair. I later spoke to this manager via phone call about the incident, he insist that the server did nothing wrong & nobody (customers or staff) heard her screaming at me in the dough cooler from the front line rather degrading. Long story short, she kept her job & I lost mine. I am a 39 year old & I have never been fired from any place of employment before this. My concern is not about getting my job back. We were both unprofessional. I feel that we both should've been fired, however I don't have a manager that I'm sleeping with to back me up like she does. This is unjust. At this point, not only should she be fired, but the manager involved with her should definately be terminated, especially if "unprofessionalism" is the primary issue. Where do I go & who do I talk to to see that this matter is seriously looked into?
