Every office I've ever worked in has had sooner or later has someone who's needed to be told by management something about clothes/behavior/hygiene that you'd think should be obvious, and it was something different each time.

If it's in response to a issue, that's constructive and helpful, but imagine some 20 something restroom safety coordinator reminding you that you'll get a rash if you don't wipe yourself as you leave the restroom unprompted.

These "helpful tips" are mostly a power play. The framing is you are an idiot that has to be told that you get sunburned in the sun, let me guide you so you don't hurt yourself, aren't you so glad that I'm here to look out for you.

I forgot to wear sunscreen the other day at a work event and I’m still bright red two weeks later.
