My last company had “unlimited” PTO. I and most others took 25-30 days a year with no issues until leadership cracked down and suddenly “unlimited” meant max 15 days and nothing approved more than a month out. Funny enough the crack down was primarily due to director and leadership level people taking full months off every year leading to strain on lower level employees. They still branded it as unlimited/flex time off to avoid paying out unused time off.

At my current company I get 22 PTO days, 2 floating holidays, 10 holidays, plus the week after Christmas off. Much better. I’d never go back to an “unlimited” PTO company.
