If we're including holidays, I've seen plenty of companies that do 4 weeks PTO + 8-9 holidays which is just shy of 6 weeks, and there some that do 5-6 weeks PTO after you've been there for a number of years.

But there are also ones where you basically get no PTO. Presumably (hopefully?) you get paid more money to work at these places, but I've never found them worth investigating.
