Some people have always worked from home. I grew up on a farm, so we lived on the job. Of course, Dad was often out in his landrover, seeing to cattle or harvest or whatever, but all the office work was done in the house.
I've been working in IT for more than quarter of a century and I've been able to WFH most of that time - I've had to cover on-call 24/7 in various rotas over that time. I've worked in international teams where we've been spread out over different countries, so whether they're in the office is mostly irrelevant.
My last two jobs have been hybrid, which works well - we are asked to go in on one particular day, do we get to work face-to-face with people, whuch means I've got a lot of meetings tomorrow, but it's a change from sharing screens, and it does make for vloser working relationships. We can go in on other days if desired - there's a desk-booking app, because we couldn't actually accommodate all staff on the same day, but there are a lot of field-based staff who travel to customer sites anyway. I'm just 6 weeks into a new job, and being face-to-face one day a week really does help with getting to know people.
Everyone has the right to request flexible working. Businesses don't have to agree if it doesn't work for the business. The requestor needs to show how it will work for the business, and even then, they may not agree. Different businesses have different needs - not all office jobs are the same, and of course, many roles cannot be fine remotely.
Of course some people take the piss with WFH, but then there have always been some people who took the piss when entirely office-based, and when you've been in a business a little while, you usually know who those people are.
Good teams mostly get on. I don't hate any of my colleagues. Some people can be frustrating to work with - different communication styles and so on. But most of them are actually all right IME, and I've made good friends, been on holiday either some, been to weddings, funerals, seen their children grow up. But even those where we've not been that close, we tend to get on well enough that we can work well together. (There have been a couple of exceptions over the years.)
if you're someone who really does hate everyone in the office, you should probably consider whether they're the problem. It's probably not whether or not you WFH or in the office.
