I was working as a stockboy in a supermarket and when we had to fill the milk cooler people would bust open a 12 pack of milk cartons and put them in one by one.
On my first day I just placed the 12 pack in the cooler and cut the plastic off on one side with my box cutter and yanked it from under it and the look of the store manager and the other employee who was training me was pure bewilderment.
From that day everyone did it my way.
The only problem with your plan is that it requires thoughtful, intelligent managers who are capable of looking at the big picture. Managers like that are in short supply.
For too many managers, any free time is only seen as lost productivity… and if productivity isn’t possible, there’s always busywork. “If you have time to lean, you have time to clean”.
I mean, yeah. Trying to teach that lesson to the “kids” under me… under promise over deliver (a bit)
Give you people some time so that they can absorb unexpected issues without too much stress- which reduces quality- and keeps you from under delivering.
It also gives them unstructured time to tidy things up or whatever so they can be optimal
