I worked for a defense contractor that had a truly unlimited vacation policy as long as you were getting your work done. We actually would get formally reprimanded and put on a PIP for not using enough vacation. All benefits started day 1 including 4 months new parental leave (fully paid; STD following birth did not count against the 4 months), unlimited vacation (no questions asked and auto-approved for the first 30 days per year), unlimited sick leave (up to 5-days per incident after which you'd transition to STD up through 12 weeks then LTD at 100%, then 70% of pay until better or moved onto SSDI exceeding the benefit respectively), unlimited jury duty leave at 100% pay (one guy that I knew there spent 4 months on a jury for a complex civil trial), dedicated paid time off to vote in every election (local, state, or federal), and a whole heck of a lot more. Had I not gotten a much better offer from a HFT firm that fully offset the decrease in benefits, I probably would never have left the company because of how amazing the benefits were. I had taken 4 weeks off for my wedding + honeymoon before I quit and my manager was talking to me about how I should still schedule another 3-4 weeks off that fiscal year for vacations at other times.
