It depends very heavily on the company management. At both my current and last employer, we had unlimited PTO and employees were encouraged to use it, the only requirement being that they get their work done. At my last employer, most people took 8-10 weeks off/year in the U.S. office and 12-16 weeks off in our European offices. At my current employer, people average 4-8 weeks and people who don't take at least 4 weeks off a year are gently encouraged to spend more time away from work. In both cases, PTO is not discretionary except where the employee's job specifically involves working on-site for a specific project or event and PTO would overlap with that period.
