I fucking love working from home. I work 3 days at home, 2 days in the office. In the office I spend at least 2 hours talking shit, correction, listening to inane shit from co-workers , absolute drivel completely detached from work. I spend at least 1 to 2 hours helping weaker workers with their work.
On Teams, I've found people ask for help less , maybe because its more formal and leaves an audit trail. Calling someone over to your desk doesn't.
When I WFH its bliss, I can get so much more shit done and on my coffee breaks I can chill and listen to Radio or read a few pages of my book in my home. On the 3 days home I work through lunch and collect my child and spend quality time with them, on my office days they attend after school and I pick them up in the dark at 6pm exhausted, my partner works in a school and is gone from 7am to 7pm 5 days a week and sees DC for barely half an hour.
As others have mentioned the down side is the work laptop is an expensive one and much better than my old beat up laptop , so I tend to use it afer the kids are sleeping for life admin and end up sneaking peeks at work emails, or doing tasks for tommrw , i.e working much longer hours compared to pre-covid when I went to work 5 days a week.
In my industry, I would resign if my firm said everyone back to work 5 days, but in London, that's just not happening as EVERYONE fucking hates commuting in London. If you can work from home for most of the week, and if you have a family, its a god send to parents who live in big cities.
