I've been at my office job for 3 months. I've pretty well got the jist of the daily tasks and such, but occasionally I'll falter and make a mistake in the system or forget a piece of information and my boss has zero patience for error. Every day I dread going in and I'm always on edge waiting for him to point out a flaw in my work. I can't quit, so I guess I just need to vent, but I hate to say if I get fired I won't be overly devastated. He says I'm doing well, but then when I mess up he acts like he just cannot tolerate it. It's exhausting.
