You miss the point, this is not personal to you.
You ask Home workers if they are productive, what else are they going to say.
Yes, some are productive, do you really think it is as high as the survey says?
It is a pretty low percent, maybe the same as in the office. 10% productive? lower?
Why is productivity of VITAL importance when WFH, but when workers are in the office, it's importance sinks?
I think it's several factors. Cost of commercial real estate being a big one, but also the relevance of low- to mid-level managers who really aren't needed--and WFH is exposing that.
So they scream and yell about "productivity" without really defining what that means or how they measure it in the office.
I actually find myself much more connected to my team than I did in the office because I'm not wearing headphones all day in an attempt to drown out the noise, and I'm concentrating on my screen, which is where all my communication takes place. No one has to wander around the office/building looking for me or for a room to meet in. We just meet where we are.
Yes--a lot of people take advantage of the situation. However, I think that is on the managers--they need to hire better people.
