Is there anyone I can call for wrongful termination?

I've been a fuel hauler in NC for 8 years. Spotless record, never had any disciplinary problems. My company recently terminated my employment for something I did not do. It's hearsay from one employee who doesn't like me. When told they were terminating me they did not have me sign anything nor did they ask for my statement. There was no investigation and no proof that I did what this other employee said I did. No one called Saftey or risk management to report the "incident". In fact, I was the first one to let safety know what was going on. I have contacted the higher ups in the company and HR has contacted me, but I want to know if there is any other recourse should they choose to uphold my termination. I would never do what the other employee has stated he saw me do. I'm an experienced professional and it is disconcerting that this is happening.

 

NC is also an at will state. I just don't see how they could let me go without investigating the alleged incident. I'm a good, loyal driver.

 

My thoughts exactly

 

I went to a store to deliver fuel. I was using someone else's trailer because mine was down. His third compartment didn't fully drop. On my way back to the loading rack I pulled over because I realized there might be product on the truck. When I got out to check it out I saw our mechanic pull up. He got out and asked if I was okay. I said yes and that I was checking the trailer. I bucket drained the first 2 compartments and there was nothing. When I went to pull the 3rd Handle I realized it was tight and that there must be product on board. I then went to the loading rack to drain the remaining product but when I checked it out I realized it was too much product and went back to the yard to see if I could load around it and return to the same store I had the retain at. Dispatch put another load to the same store on me and I loaded around the retain and took it back to the store. The mechanic told my TM that I pulled the handle and spilled gas all over the side of the road. It seems to me that if that was the case, risk management would be called. Or safety. None of these things happened. In fact, I'm the one who called safety to report that they were terminating me for something I didn't do.
