I feel like you are my coworker... I know you're not but he is in a similar situation. I want to feel bad for him because he is sucking hard but he also puts in no effort to learn his job, be proactive, or even remember the stuff he's been taught. I've suggested he take notes, and when he asks questions I ask him what his notes say and he doesn't know where his notes are (some do exist because I have given him some of my notes when I was training him). Yet he also complains that everyone else knows how to do more than him and somehow still thinks he should get a promotion. What is it that you do? Knowing a little about what your office does might help me formulate some advice. It can be hard to integrate with a group that already exists and has worked together a long time, don't try to force anything though, it's only been a couple of months, so your opportunity to work yourself into the group dynamic better may not have presented itself yet.
