Where I work we don't get bonuses, but usually we get cost-of-living increases to our salary every year--it's small, like 2-5%, but obviously a different number when you compare them. For a couple years, when the economy was so bad, we were regretfully informed that we wouldn't get even that. Then our boss happily informed us that the increases were back--she didn't have anything to do with them personally, but obviously the mood was supposed to be, "Hey, that's great!" 'Cause it is.
My troublesome former co-worker Mike started to raise a big stink because he didn't think he'd gotten his increase. Like, personally offended, something horrible has gone wrong, contradicting the boss when she said they'd come through, etc.. He opened up the website that said how much he was being paid now and was like, "See? It's the same as last month!" Finally he was prevailed upon to actually do the math between the old pay and the new pay and found that the new pay was, indeed, 2% more.
Honestly, we all know 2% isn't that much more, but it IS more, and since previously we hadn't gotten more at all, this ought to be a good thing. And him being such a whiny baby about it just brought home how small the increase was, and made him seem really ungrateful, I think.
