Please, tell me what I did wrong?

Yes, I believe my days are numbered, here. I refuse to badmouth them. I have not done so, with any other employer, I'm not going to start now. I simply wanted to ask for some objectivity, and I believe I got it, here.

As far as the termination from Flying J, they informed me, when I told them how long I would be gone, that FMLA required them to terminate me after 12 weeks, but they would be happy to re-hire me when I went to return to work. It just so happened, that the economy went south during this time. I understand them not hiring me back, due to the economic circumstances, I am simply disappointed, that the Lead Driver who took over, right about the time I was to be coming back, had a different agenda, and wasn't enough of a man to tell me the truth. He said, that although he really wanted all the drivers to be based out of HIS traditional Plaza, not the one I worked for, he was going to process my application, but never did. He should have been man enough to tell me, to my face that he had a plan, to downsize and save some money and wasn't hiring. He left me believing I still had a shot at re-hiring, and some time was wasted, and money lost, while waiting to re-hire, and then NEVER getting that call. I always thought he was a really decent boss, based on everything I heard from his drivers, and my dealings with him were always positive, until he jacked me around, about the re-hire. Oh, well I have to put it behind me and move on, just like I'll have to do with this company I am working for.
