When I was hired on for my current job my boss explained that they don’t require any proof to use our “medical time.” While vacation time should be put in with a bit of notice, medical time was ours to use whenever. Literally said, if you wake up after a stressful few days and just want to enjoy some fresh air, just put it on the shared calendar that you’re using some medical time. It can be as little as 1hr, it doesn’t matter.
(Small company in the US btw)
My wife was so mad at me when I explained this to her. She said the chlorine smell would give her nostalgia and I ruined it.
