> Some companies offer unlimited PTO. The catch is

...that unlimited PTO can't be accrued, and is usually still subject to approval to use like regular limited PTO, which makes it an easy mechanism for arbitrary favoritism by managers without the fallback that if your PTO isn't approved you at least keep and accrue your balance which can be used later in your career or cashed out, and which the company then has an incentive to allow.you to use to clear the liability from their balance sheet.
