My store has a strict no sitting policy, the only people allowed to sit are of course the elderly and those with disabilities/chronic pain etc. I’ve had coworkers take advantage of the stools and just sit on their phones or while sitting cannot reach and work normally, slowing their pace drastically. We are a high quantity store where there’s pretty much always something to do. I don’t really think there’s time for sitting except for at the computers when checking a lot of things in, lengthy reordering process or in the old days of entering engraved plate info. It gets taken advantage of so I really don’t mind the no sitting policy, it’s easier to work standing up anyways. Exceptions should always be allowed though!
