Today some coworkers and I were assigned to do some menial stuff. Me and one other guy did everything while two others sat on their phones for an hour. We would have been done in half the time if they had helped - in fact we didn't finish.

Later, I told our boss and he said "Thanks for being a tattletale" and took a draw on bis cig and I just walked away annoyed. Now I don't know whether to be embarrassed for "tattling" or angry at someone.

If I hadn't done anything, I'd probably be disappointed in myself for letting myself get walked over. I guess I should have confronted the two guys myself but I doubt anything would have happened and I'm not in any authority over them.

What should I learn from this situation /adv/?
