I know what definitely doesn't improve productivity. Constantly talking and arguing about the what's, who's and whataboutisms of it all. We should all just get back to work, remote, on site, hybrid, anything.
We are pretending to work alot to not stir up social unrest on the work place among other types of staff.
But like there is no need to actually believe in it ourself.
A related aside: I've noticed anecdotally that as you become more senior you get pretty good at feeling out what that number is for each of your teammates and it becomes a pretty useful metric to leverage in your day-to-day toolkit. I'd be curious to see what a workplace would look like if folks were actually allowed to be transparent about that (without repercussions) rather than it having to be guesstimated.
