People need a lot of time off. More than they used to. When people work very hard for long periods of time, there should be some accommodation for a personal life and time off. We need highly dedicated people who will put in the hours necessary to make this company competitive but everyone needs a rest now and then. This is becoming increasingly important.
Most people work pretty hard.
Maybe too hard. You should manage people's performance not the people themselves. It makes people too defensive to be judged personally. Therefore managers and employees should jointly focus on what is or is not getting done. Then figure out what needs to be done next.
