Boss asking workers not to put OT worked on their timecards, asking us to keep track of our 1.5 time as “PTO” off the books.

E.g. you work 1 hour of OT on Monday. You do not put it on your timecard. Boss lets you leave 1.5 hours early on Tuesday, and it's on you to lie on your timecard and say you were actually present all day Tuesday when you weren't in order to take this “PTO”. Makes the boss look good to keep overtime down. No real papertrail to indicate it's happening. Staff complicit, and bearing all of the risk. No way to justify hiring more staff, which we desperately need. What's a worker to do?
