3. "Professional." Unlimited vacation time! Take as much as you want, when you need it! And by that, we mean that peer pressure and American work-a-holism will ensure that you will never take advantage of all that "unlimited" vacation time and will feel guilty every single time you do. And if you happen to start taking a lot of that unlimited vacation time ... well, you're just not a team player, are ya?
Personal note- Professionals are given unlimited vacation time at my office. I often have to specifically and repeatedly tell the younger professionals to take a friggin' vacation already because burnout is real.
