Every job I’ve had does not pay accrued PTO no matter how you left the company. Most states do not require companies to pay out accrued PTO.
In practice this just means that you can take two weeks and still get paid. You can forgo your vacation in some instances, but you still get paid out the vacation money. I used to do that when I worked part-time in college and was short of cash for whatever reason.
