> if he worked too many overtime hours (which came around from time to time), would get into the next tax bracket and it wouldn't be worth it
By "not worth it", I suppose you mean that he valued the marginal increase in income less than the marginal decrease in free time – which is entirely subjective and different from person to person? I don't see your point.
In the higher tax bracket, he didn't work enough overtime to offset the increased taxes and ended up with a smaller check than if he worked less. At least that's what he claimed.
