Straight pay for overtime is stupid. Spin it anyway you want but you are giving up money, numbers below you, or both for the "opportunity" to work overtime. Dumb.
Before people respond with the inevitable "don't bid it", consider that whether one bids it or not it affects you. Additionally, I have gotten it on a few occasions when I didn't want it because it was part of a line that had the requisite dates off.
Carryover should go.
