I always felt like I was letting my team down when I was taking time off. So I took a lot less time off.
Ideally I'd prefer an environment that had an open schedule and also expected employees to take a certain amount of time off every year.
"required"
If you really don't want to you don't have to.
But the point is to allow employees to take time off without feeling guilty, while still allowing them to control their own schedule.
Funny. I wonder why.
I grant you that this is a hard model to scale. Not sure how you'd do it with 1,000 employees. Thankfully I have never worked in the bowels of such monsters.
