Previously, as a manager in a manufacturing environment, where many line staff took "3 day" weekends, due to hangovers / late night returning from weekends, I asked my supervisors to always come in on Monday morning if they were sick (but could still drive). They could come in a bit late, stay and hour, "show" that they were ill, (but stay away from meetings / people) and then go home, (for the rest of the week, if needed). I would also pay them for the day they showed up for the hour.
Normally I agree that we stay home if sick, but I needed to change the culture of so many people call in on Mondays.
Now, my criteria are -- get out of bed, get dressed, move around, drink coffee. If I feel that I should lie down all day, and / or not drive, then I call in sick. If I think I can watch Netflix all day or even run a quick errand, then I work form home or go in.
