Mine is - DO NOT go to the building you work at. Like if you’re a retail worker, it is not wise to go to the store you work at or the restaurant. Because they see you come in shopping for whatever reason, they’ll possibly be on your ass about you being able to come in and shop but not work that day.
I try not to waste the day, and actually leave the house to do fun stuff.
I also try to completely avoid work email, slack. Generally the less I consciously think about work the better.
There are no hard and fast rules, but my approach is to pretend like I’m retired and living my best life.
