> This is like the unspoken mantra of "unlimited vacation" really being only 2 - 2.5 weeks. I think it depends on your company and management chain. When I worked at Netflix I took more vacation than every before. I'm not even sure how much, since it was untracked, but definitely more than 4 weeks a year. Our management made sure to set a good example by taking plenty of vacation.
Netflix is the exception, not the rule. Take a poll of what "unlimited vacation" means to most companies with the policy, and you'll see 2-3 weeks being the overwhelming response.
Kickstarter removed it's "unlimited vacation" policy because it found that employees were not taking enough vacation. This seems to be a strong statement from the company that they want to encourage vacation taking.
I can find no evidence that most companies with "unlimited vacation" policies are trying to limit the amount of vacation for its employees. It would be great if you could furnish it, as I'm interested in this topic.
