I find the Teams more interrupting: "you avail for a call?" and then I get dragged into an irrelevant meeting. When working at my desk I do get interrupted but also some people actually have the brains to notice that I am actually working and maybe the most they say is "I'll come back later."
Just ignore 'em. Set yourself away and mute notifications. This isn't really a thing you can do in real life when people accost you while you're trying to get something done; they'll move around in front of you and wave their arms, make gestures for you to take off headphones, etc. They can't do that in Teams. They've got to wait. Its probably the single best productivity enhancer you get from WFH.
Sorry, but that's just how it is, I know you all can't understand this. Better chair, better desk, dual monitors, better view out the window, people clean up the place, the food is better. Also I need lab space.
Interesting. These are the exact same reasons I'd give for being remote; I have far faster equipment, more monitors, a bigger desk and a more comfortable chair at home than work would ever splurge for. Its cleaner and smells nicer which helps me focus. I can prepare and eat a fresh lunch rather than bring in something to microwave. Most importantly, I have personal space and a room with just me in it to work -- something you definitely can't get at the office.
Also, working in the office and doing home stuff at home keeps the two SEPARATE! This is important. When the pandemic started we got good advice from a remote worker who works at home all the time. And the first rule was to keep work and life separate. No 24/7 on call bullshit, when the work is over shut off the computer. Same rule for the office - don't take work home with you. Being at home means someone out there may think you can now do the 7am meeting, or the 7pm meeting.
My jobs have always 24/7 on call type situations, so that aspect of it doesn't really change either way. That 3am hotfix deployment to fix what an external developer around the world just broke still has to happen regardless of what I building I was in 12 hours ago. Being remote just means my entire life doesn't have to revolve around being physically present at the office -- I'm not chained to being there during the hours everything else is open, so I can do things I could never do before like visit a dentist.
