Yes, but I'm sure it's ultimately their choice. Does the board of directors or stockholders send the CEO a memo that his car is not in the parking lot long enough for their liking?

If the CEO wants to work him/herself into an early grave, that's his/her choice. But to force employees who, let's face it, aren't going to be able to enjoy the fruits of their labor like the CEO will, to give up large portions of their personal time to improve the wrong metric? That's unreasonable.
