pikachu - I'd be ticked off too if this was a planned event and no one had told me. Is it possible that it was a spur-of-the-moment thing that all took place when you were out?
famita - that's too bad that your boss isn't appreciating all you do. My daughter didn't like her first job as an office manager because of her boss, but he was good about giving her bonuses for the things she did that brought extra business into the company. She got $100 for every client she signed while he was out of the office. I'm terrible about bringing up money issues with bosses though, so I don't know what the best way would be for you to bring it up. Is your boss aware of how much you're doing?
