Why do you hire someone with a criminal record and no one can trust?

So at my oh so lovely job I work with someone with lets say is the most difficult person to work with I have ever encountered. So this guy got mad at me and another employee on Friday because we questioned something he was doing. We just wanted to know what was going on because there is nothing in the account notes. Well he decided to blow up at that and tell the repo agent we were questioning that we had a problem with him. The repo agent asked us if we had a problem and we both said we didn't so the repo agent tells us that the manger said that we had a problem with him. We just said no no its fine don't worry about it. So this other employee of mine calls the manager and asks him whats going on and the manger responds saying he isn't working for Nebo right now and he'll talk to him on Monday.
Well Monday comes around and he pulls this other employee into an office to talk to him. Then he pulls me in to talk to him. I tell him that I don't agree with him, i don't trust him, and that he basically is a crappy manager. Instead of addressing any of the issues I bring up he insteads just says look at my numbers and how good I'm doing. Come to find out my numbers were twice better then what he currently has. But whatever there is no point in bickering who is the better manager. So basically he wouldn't address any of my issues or concerns I had so I said forget it and I walked away with nothing resolved. Now I'm currently looking for a new job.
I called the old Collection Manager who is now a manager of another credit union. He said he'd write me a letter of recommendation to see if that'll help me get a job elsewhere. I even told one of the branch managers I'd come work for him as a teller. At this point I just need to get out of the collection department because I know that manager is doing something and that is why he is getting mad at us questioning him. I just can't figure out what he is doing. So yeah that on top of everything else on my life is just weighing me down. I'm exhausted and have trouble getting out of bed in the morning! So hopefully i can get my life figured out. Thanks for the vent fest blog.
