The ups and downs of good work

There's a problem with being a good worker, doing a good job.
There's perks to being a good worker, doing a good job.

Perks:
raises, praise, recognition

Problems:
you have to pick up others' slack, you have to cover others' butts and it gets to be quite a hassle when you have to cover everyone.

I'm sick of hearing, "You do such a good job, could you do this because so-and-so can't get to it/has problems with it/is a brainless waste."
