I've a friend who was told that he needed to take a vacation. Not in the "You're out of line" sense at all, but in the "We expect our employees to use their vacation time, and you've been working hard lately." He's also been told to cut back on the his hours, as his bosses didn't want him to sacrifice his personal life.

Usually when you hear stories like this, it's because the employee is screwing up. In this case, it's because the higher ups realize that proactively preventing employees from becoming overstressed is a good way to keep employees.
