A company like Fujitsu already has offices in nearly every time zone. The average meeting there already has people who are joining remotely. Teams already have to coordinate and managers already have to manage on the other side of the world. Letting people join their daily standup WebEx from home instead of whatever office they usually go to doesn't really have much impact on that workflow (especially since ~20% of the company already does that on any given Friday).
What WFH it does have is an immediate and direct impact on is cost.
If you're in management and you see that cost reduction in the numbers, productivity appears unaffected, morale appears unaffected (and some people even say it's improved) can you justify to your superiors not continuing to give people the option to WFH where possible?
In my company, my productivity skyrocketed, while that of my work colleagues crashed. It largely correlated with things like tech literacy and being open to change. Where I work, there are a few people with who invested in nice WFH setups, work-life integration, and all the things needed to make this work, who found productivity going up. And then there is the majority of people who stubbornly still refuse to even use a headset or learn to use tech, and are just waiting for the office to reopen.
Outside my company, it's not quite the same split, but most people are dipping their toes in rather than diving headfirst.
Honestly, this is a very patronising view. I understand that a lot of people here are strong permanent WFH advocates, but it doesn't fit everyone.
My home setup is pretty good and I'll still be first in line for getting back to the office for a variety of reasons - and there's many others like me.
If you think that means I'm less "tech literate" and not as "open to change" then that's your perogative.
I don't think that makes me resistant to change - I just consider it a change for the worse.
Even with working more and having a fairly short commute (20-25min ea way), I find I have a lot more time for (solo) hobbies and tinkering. Losing 4 hours a week to commuting and probably another extra 3 to lunch (over quick lunches at home whenever I want) adds up pretty quickly.
I expected to hate WFH, but I like it a surprisingly large amount.
Don’t overlook the stress of living during a pandemic. Has absolutely ruined my productivity during WFH.
Now, that things calmed down and they started "Kurzarbeit", basically reducing working hours where the state offsets salaries, the company insists that everyone returns to the office. Old ways die hard it seems.
As for nice chair depending on your employer I would ask for the one from your job if its sufficient. I was able to take mine home. Its just gonna collect dust otherwise.
And, as others have said, childcare and other arrangements to allow you to work without distraction.
It is going to be hard to get good data on this, since so many people are not just working from home but are also caring for children or stress out of their minds due to a pandemic.
From talking to people, it seems that senior engineers are doing well and junior engineers have lower output. I think this is reasonable. People who need more hand holding will have more friction separating them from help. People who already have a strong background have fewer distractions and can focus deeply on code. Whether this sums to an overall positive or negative change in productivity, I have no idea.
