I'm sure some companies are doing it properly, but I think for the most part it's 'unlimited holiday if you get the work done', which turns into 'holiday if you get the work done', and there will always be enough work that it never gets done. At previous company we switched to the 'unlimited holiday' policy, I asked my boss what the real limit was and she said if it was anything over 27 days (the previous amount before being 'unlimited') then the manager would have to sign off on it, which basically wouldn't happen. I'm experiencing a similar thing at my current job where when I asked what the office hours and lunch hours were I couldn't get a straight answer, it's kept intentionally vague so that when it gets to 5 you don't go 'well I'm off home, bye!'
