Yes. Can you? This is not the scenario that happened. What happened is that Tuesday is a normal work day. Not a paid holiday. Ergo, if you want to not come in on Tuesday, you either have to spend vacation time to take the day off with pay *or* have your pay docked for the day you didn't work.
Which is completely normal, right?
No, it isn't. The concept of "Salaried" means, generally, you get paid regardless of how much or how little you work.
The fact that work will be "slow" doesn't really matter here.
It does, in fact, because not paying salaried employees is illegal. They can voluntarily take unpaid leave, you can't just not pay them. I know labor law is a complete mystery to you, but maybe consider that next time you are about make a fool of yourself.
