You've had some pretty worker-unfriendly employers then? I too have been paid out unused PTO by every company I've ever worked for (and my current company pays it out too), and I've never worked in a state where doing so is unfriendly.
Well that's a silly and expensive policy. It means that people take long vacations as they're leaving -- but they haven't quit yet, so the company's still on the hook for employment taxes and health insurance. It'd be cheaper for them to just pay it out and then get the employee off the payrolls.
