Today I found out that US companies are not legally required to give employees paid days off for public holidays.
I was searching for info on which countries have fewer paid holidays than the US (I work with US people a lot and I am keenly aware that they get days off significantly less frequently). And I found out that about 25% of US workers have zero paid days off of any kind, holidays or vacation. And this is legal.
I'll just go and lie down now.
