Two anedoctal stories of mine: a) I do some consulting for a healthcare company, and bill them by the hour. It is very difficult to reach 60h/month, I managed to get that once, and it translated to an incredible amount of work. Initially they were worried about the cost, and put a cap of 80h/mo, but I never got even near that. b) Back in the 1990s I worked as technical support for a small ERP company. I had a colleague that kept a frantic pace the whole day, did a lot of overtime, always buried by work, complaining, etc. He had so many booked overtime hours, he took a 3-week vacation solely on them (in Brazil you have 30 day of vacation per year, as well). Those 3 weeks were the most quiet I ever saw in my work. I even found the K&R book and learnt C (I was really amused to find that UNIXes came with a free compiler. Development tools used to cost several thousand USD back then.)
