Just mentioning this without opinion: centralising discussions, and placing the power to moderate those discussions in the hands of a small number of people, is exactly the problem Lemmy was created to solve.
To be able to see the rest of the fediverse (i.e. all the other Lemmy and KBin servers) your home server must be operational, and must "federate" with them.
The admins of each server can decide how much of the rest of the federation (i.e. all the other Lemmy and kbin servers) you can and cannot see. They could choose to just allow everything - however, you will quickly find yourself swamped by abusive and bot accounts. They could also choose to allow nothing, limiting their users to just the one server. Neither of these extremes are optimal, so the admins have to decide where they want to draw the line.
If you are able to find a server owner whose interests, or at least their philosophy, aligns with yours, this will give you the best experience. For example, the server I'm on (lemmy.blahaj.zone) is heavily moderated to create a safe space for LGBTQIA+ people.
If there's no business reason to have you in the office (other than bums on seats, which is a terrible business reason), maybe ask if there's any way you can do four WFH a week? But definitely start looking for a new job, and remember, it's easier to get a job if you already have a job.
My mainstream five and the reasons I've picked them:
BRIAN BLESSED (frankly, I believe he should be in everything)
Craig Charles (he's very funny and witty, plus he should be in more stuff IMHO)
Jeremy Clarkson (he'd cock everything up and be good comic relief)
Joanna Lumley (she gives off the air that she's down for anything, and she was amazing in The Goodies' Audible pilot)
Richard Ayoade (he seems an extremely good fit for the show, and reportedly wants to do it, he's just in such high demand nowadays which is a good thing)
Sue Perkins was formerly one of my five, but she's going to be in Series 16. :)
I also have a far-less-mainstream five: Tom Scott, Chris Joel, Gary Brannan, Matt Gray, Will Seaward. #MysteryBiscuits
The forgotten mug of tea is a scourge on British society as we know it, and any means necessary should, nay, must be used to prevent this, up to and including self-heating mugs. #ChangeMyMind
FYI: Blahaj Lemmy, the instance which we are currently discussing, is also moderated as a safe space. Not entirely sure how you ended up here, but welcome all the same! :)
Why isn't Malcolm Tucker swearing? It's an absolute omnishambles!
