Which brings me to the next point which is that I do strongly believe that productivity will not take a massive hit overall - as much as managers like to think engineers are like factory workers assembling a toaster, my personal observation has been that we’d get things done when they are needed (within reason) and would subconsciously pad out the time when we can afford to.
A long sabbatical would make me immensely happy and I think more focused when I’m actually working. Importantly if we all prepare for the same full on break that’s scheduled that’s more manageable than individual engineers taking time off at random intervals and having everyone cover for them.
Just still spitballing so for sure all comments are appreciated.
