These people are presumably paid to go into the freezer. If they weren’t going into the freezer that would be a problem. It’s going into the freezer and doing whip-its is the problem.

I was going to say then that you’d need to prove the person was actually doing whip-its and not their job, but I’m guessing this is America and it’s not actually required to have a reason to euthanise underperforming employees.
