The ending of Covid restrictions is one thing but it seems to ushering in the mindset of 'just get on with it' if you're not well. One thing I haven't missed over the last 2 years is picking up every germ known to man from the open plan office, with people coming in with all kinds.
I had Covid in January and felt quite rough but worked from home. Prior to 2020 i'd have been obliged to go into the office with a virus and infect everyone else with it. Sickness policies mean you can't afford to take many days off in a lot of places, or you won't get paid in others.
It's a wrong step if we haven't used the last two years to change the way we view sickness. Okay, it's one thing going into work with mild cold symptoms or something, generally, but it makes a big difference to virus circulation if people who can work at home when they're ill do work from home. No doubt some will take the piss but that's for line managers to deal with.
If you come in clearly unwell (when you can wfh) you should be sent home.
