Unlimited PTO is more an American thing in my experience. And is never really unlimited as you will be judged when using it. In Europe it's common with 5+ weeks of vacation, which is also often mandatory by law to take.
well, what can I say, this company had a real problem following the union agreements and EU laws: no paid extra hours (on-call), no notice, no paternity leave according to local laws, etc. On the other hand, was really adamant to keep the 9:30 stand-up meeting for the sake of face time.
