Here where I live we don't have mandated by government bathroom breaks, yet my employer lets me go whenever I want.
Go search https://www.reddit.com/r/antiwork/ for “bathroom” and you’ll find plenty of examples of low wage workers being limited in how long and how often they are allow to relieve themselves.
Is it maybe the point that not every commonsense-ism needs legislation backing it, IF it is truly respected and honored universally as common sense.
Or is this a news item because there are tyrants who forbid workers from drinking water and taking bathroom breaks? If so, that's bizarre and sad.
