Social interaction - I get plenty of that and see work friends socially. Not everyone relies on work for social interaction and for a lot of people the social interaction side of work is very difficult. It can be so difficult they can’t work in that environment. It’s a benefit to YOU. Not everyone else.
Collaboration - that’s not a fact. That’s your opinion and may be your experience. Not mine. Not everyone’s. I have worked for international companies where teams are split all over the globe. Due to time difference some never spoke in person. Still managed to collaborate. Companies have been doing this for years.
Work set up - yes could be a problem for some. Not all. I don’t mind working in my bedroom at all. I know lots of people that would prefer to wfh, without a dedicated office but are still happier than travelling to work every day. I don’t know anyone who has been forced to pay for equipment they need for their employment. Again, doesn’t impact everyone. So still no reason, that it would benefit everyone to be back in the office. Those that really hate working in the space they have available can find a job that’s not wfh.
Everyone on the same wavelength? Your experience. Not others. If companies are good and communication is good, you don’t need this.
Sense of belonging - It’s actually really easy to not be disconnected when wfh. Infact, my experience is that people are more open and honest during discussions when there’s not an office full of people that could over hear quick discussions between team members.
Training - Again international companies had perfected this before covid. If a company still hasn’t worked out how to ensure their staff are trained, 3 years after the first lockdown, the company is the issue. Company banter, for a lot of people is painful, especially those with ASD. Diagnosed or undiagnosed. It’s not something everyone enjoys or wants.
Being seen - This is important, for companies that refuse to change with the times. Any decent company will have realised years ago, that being seen doesn’t mean you are doing your job.
Being able to disconnect - I don’t know anyone who has this problem. They actually disconnect more. They have no long commute. They switch off at 5pm and then straight downstairs into family life. Rather than getting in at 6-6.30pm (later if traffic is bad) getting home stressed, rushing to put dinner on/ kids activities. They get more family time. Your experience isn’t that.
Your list is a list of reasons that YOU miss the office. So still not answering why you believe other people should be forced to go in more. Unless your reason is ‘I think other people should do as I want them to because it suits me’
