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"

somewhere else.

What's the problem?

Is he hinting something or breeding resentment.

If I'm such a goof, then why am I getting the highest raise out of all 4 of my co-workers in my department?

This doesn't make sense to me?

It's just he has personal problems, our supervisor called him on his bs'ing, and now this same guy's telling me they know im a hard worker but kind of think im a goof.

I also have been told that this same co-worker can make things up.

Who do I believe and why will this keep me up?

Is it WRONG I'm 27 and work in the mail room making decent salary and working my butt off?
