Have pretty much worked 100% from home in my current role for last 5 or so years. We used to have quarterly onsites over a day or two, with an occasional social night out arranged, but not had one for well over 18 months.
In my previous role I was away from home a lot, last project I was on was in Aberdeen 5 days a week (I live on the Kent coast
) which was an absolute killer and led me to taking my current wfh role.
Can't see myself ever wanting to go back to anything that requires even a once weekly office visit. Why waste hours commuting when I could be working, and why work all day when I can go run, swim, do the school run, do whatever during the day around my work. Felt that way pre-lockdown, all lockdown's done is reinforce how wfh is entirely sustainable and at least as productive, if not more so.
I work with a lot of consultants who were previously on client sites most / all week, had zero home life, spent hours travelling, didn't see their kids etc. and had become totally used to their work / life balance being non-existent. Lockdown initially threw them - they struggled with not being in an office environment - but over the last 14 months they've adapted, so much so now most can't see themselves wanting to go back to 'normal' and miss out on breakfast with the kids, school runs, lunch runs and a sensible work / life balance.
That said, most of the people I'm referring to are older - late 30s / 40s. Think the younger crowd are more keen to get back to the social aspect of getting back into the office.
