I currently work for a multinational with an unlimited vacation policy and it's pretty obvious people in places where PTO is protected by law (i.e. not the US) take far more.
It's also yet another way to ensure people who know they can just walk into another job (or that they won't get fired/laid off/never promoted) take loads of vacation, while people who _really_ need to be sure they stay employed or who might be having a harder time at work are always afraid to ask for it.
Buddy of mine worked for a company with unlimited PTO until recently. He would take 2, 3 months off because, as he put it, "I had them over a barrel" (he is extremely good at what he does). His colleagues, for the most part, did not.
