You cannot really compare a production line to a warehouse. Production lines cannot function when people leave their position at random. On the other hand, there is no pressure to work as fast as you can, because the speed is determined by the production line (and needs to be humane, of course). When you are a picker in a warehouse, the situation is different. The packages can always wait a few minutes. But if I don't want people to piss in bottles, I have to make sure they will not have to compensate for the time lost by working longer/faster.
