What's your dismissal policy like?

It's awfully nice of you to keep your coworker afloat, but perhaps you should seek assistance from your immediate supervisor. After two months, either something is really not clicking with this guy, or your coworker just doesn't care to do his job. You shouldn't have to pick up that much slack. Good luck, OP!

Unless this position is brain surgeon, just fire them.

Yikes... Maybe the boss can do something about it?

I don't understand how someone can work for a company for two months and still not know how to do their job? Something isn't right about that. Talk to your supervisor. You don't get paid for two jobs, stop stressing yourself.

Not sure if FYL or YDI. You *are* the one training him after all. Maybe the problem is that you keep doing his job, and thus depriving him off opportunities to learn. Sink or swim, baby.

He has mastered one skill: how to get you to do his work for him.

Either you are a bad teacher or he is a bad learner/freeloader

Oh that sounds familiar. That's been my life for the last THREE YEARS. We can't keep a newbie longer than a couple of months because they're all fucking idiots. I know it's not my teaching, my manager says I'm a great trainer. We just keep getting morons.

I'd try to talk to your higher up, and see how the situation can be fixed.
