I'm reminded, MBK, of reading about education. Here schools have been closed so that students have been doing "remote learning" - because it's been put in place hastily and ad hoc, it's really not remote learning, but state-supported homeschooling. Anyway, people were concerned about the performance of children with time away from formal schooling.
It was pointed out that after the Christchurch earthquake, children had 7-10 weeks off school - and there was no remote learning or homeschooling at all. And the results of the high schools on exam were... better! Likewise, our own children could miss an entire semester, and still get more total hours with a teacher than Finnish schoolchildren do - and they do better than ours.
In my own (now suspended) work as a fitness instructor, I see this all the time. People think that if one hour of endurance work or a set of 10 is good, then two hours or a set of 20 must be better. And it's just not so. As you add work you get diminishing returns, and then eventually negative returns - the person becomes weaker, dumber and so on.
It is of course the same with work. Unfortunately some people are locked in an unproductive mentality. In my experience it's usually the less-skilled managers who think like this. They're dimly aware of how unproductive they are, and try to compensate by working more - and working everyone else more.
