The Verge reports that workers at an Amazon distribution facility are “forced to pee in bottles or forego their bathroom breaks entirely because fulfillment demands are too high.”
While this is horrible, and demeaning, it’s still just employees peeing in bottles. It’s not THAT big of a deal, right?
Thus, denying employees bathroom access (either directly or functionally) in the name of “getting the job done” (or otherwise) almost certainly violates OSHA.
More critically, however, suppose instead of bathroom breaks we’re talking about the removal of guarding on a piece of industrial equipment. Yes, you can make more widgets more quickly without guarding. But, your employees like leaving work with the same number of fingers and toes with which they came to work. And you should prefer that, too.
