Said they docked me 4 hours off my time for staying over a half hour, when they told me to. Then asked me to come in on my day off

I got a message to come in today as someone else had called off and I went. Get there only to find out they docked my pay 4 hours for staying over yesterday and cleaning, they told me they wanted it spotless and I told them I had no time unless I stayed over a bit and I did. Half an hour. Fuck ‘em’ I’m not cleaning shit anymore. I tried to make that place as clean as a home for me since I’m the only downstairs worker but no one gives a damn
