My kids socialising has never centred around my working life.
My kids are older so do their own socialising mainly. But hybrid is allowing people, who work for me and have younger kids, to spend more time with their kids/friends and wider family. More time to take their kids to hobbies and so on. They are socialising more with the people who are important to them.
Dd has just finished her first year at Uni. Most lectures were in person. Ds is still at school, so socialises with school friend inside and outside school.
I think if you are a parent who likes social isolation, then you would be more likely to isolate outside work, if you have to work outside the house.
I do think fully wfh (hybrid or full time) doesn’t work for all people. It obviously doesn’t work for all job roles, even in the same company or industry. it’s very individual. But there are plenty of jobs that aren’t wfh if it doesn’t suit.
Not sure I agree on people who wfh being left behind career wise. I think it is happening. But I can see in my company and the companies we deal with, these are the people that were really effectively engaged in pursuing promotion when on the office.
I know some people who wfh 4 days a week and still get recognised for their contribution and have been promoted. I know some who work 4 days a week who haven’t been. The ones that haven’t, come in don’t really speak to many people, don’t want to engage in meetings, won’t stretch themselves or come up with ideas for improvement. But they were like that before. They want to come in, do their job and go home. They wouldn’t be in a different position if they were in the office full time.
