Financial talk

Is my co-worker admitting her was wrong? What should I do? Should I be worried about my job? Ladies: Should I be worried about my job? Ladies: Should I be worried about my job? Why am I feeling bothered by this guy at work? And do you think he's just saying this? Ladies: Why is this bothering me so much? Co-worker depressing me? I work as a mail clerk at a company, I get lots of compliments, I am known for being a hard worker, but lately a co-worker of mine has been telling me some people (didn';t give names) think I'm a "goof", meaning I have made some dumb mistakes on the job. For example : One time I was going to be out for 3 days, I made the mistake of emailing the entire company that..... And he said personnel "laughed at me".....if they laughed at me, how come they say hi to me every time I see them? Also, I guess they might have said it because I would get things, materials at a warehouse and sometimes bring the wrong things back....... The thing is, this same guy keeps telling me "don't stay here for more than 5 years, you probably won't move up" and stuff like that.....and I told him the truth. I am a college grad who has his own career aspirations and this is the job I like that I can support myself with and pay the bills. But yesterday, and today he said "You can make more money" 18 minutes ago - 3 days left to answer. Additional Details 16 minutes ago Then today we had a big argument, because I made a couple mistakes on the copier and he said he's tired of me making stupid mistakes, then he apologized and said he wants to take me out for a beer. But he contradicts himself.....What the ****? Also, we had been told it will be a while till we get a review. He said I was the weakest link in the department. Then why did I get the highest raise? My boss knows about him, me and this kid DO get along, but he takes his personal problems out on others....... I work hard, this is really bothering me. 15 minutes ago Should I quit? He said I seem distracted, and wants to know what's on my mind and I told him if he's got a problem to go to our boss and tell him how worthless I am. Then he said im not worthless......He's just pissy and admitted he was acting "like a *****" and that's how he can be. Should I accept his invitation for a beer? I dropped it, but it's like what the hell? Does this drama go on in a work place? Is it ok, I go for a beer with him, he insists because he wants to apologize for being an asshole he says. Is this fine?
