The last 10 days I've been in an open plan office instead of my home office I've used for 8 years.
I've had to trade a 5k ultrawide monitor for 1080p, an Aeron for a cheap chair the company bought secondhand, desk at a height that's comfortable for one that isn't (I'm 6'5), natural light for fluorescent and 500ppm of CO2 for 1200ppm+. And a 10 second walk for a 45 minute drive each way commute.
I don't even think CO2 is on anyone's radar, but some complain of headaches and many seem really lethargic by late morning.
And everyone in the office uses cloud software, but there's a distrust of remote working. I was hoping this battle would be won by now, I'm almost at the point of thinking it should be encouraged by legislation.
