From a manufacturing standpoint, having to add an additional crew to a 24 hour schedule would also mean additional handoffs and opportunities for things to be missed. In my experience, manufacturing shifts are typically not more than 12.5 hours, but may bump to 16ish if there are calloffs and the like. My understanding is that in the medical field, handoffs are viewed as large opportunities for mistakes to happen through miscommunication, and that's at least some of the justification behind having people work 12-24+ hour shifts.
