That’s true, but rotating less frequently would be better for everyone. As example rotating every month has the same effect, but allows your worker to get a good rhythm.

The Job description OP posted is weekly rotating shifts. Quarterly rotating g shifts is a good way to prevent getting stuck in one shift without destroying your employees.

Youre right in terms of using the machines. However, it doesn’t make any difference for the machine who operates it. If people operate it while doing their normal first shift like they do every week or if they operate it in the third shift, because they have it this week makes zero difference for the machine. Rotating shifts has absolutely zero benefits and destroy your workforce.

German here. Here rotating shifts in assembly, jobs is quite regular. We also have unions for the big industries that do rotating shifts.

Wouldn’t be a loss IMO
