> if a single week of overtime will help you meet a critical deadline In my experience, every unit of overtime is followed by a larger unit of "undertime" where the team (usually subconsciously) goes through a period of low productivity. The ratio is often as high or higher than 1:2, so a week of overtime can result in two weeks of undertime. I present this as a fact when project sponsors request that the team work OT so that they're aware that they're trading future productivity at a loss for productivity today.
