I was WFH for about a decade too. I didn’t work from my bed, but I sure as hell took meetings that I didn’t really need to be in, or was more of a passive participant in, from bed. Always close to my computer (on the same floor) so I could get back if I needed something, but those were the best useless meetings.
But I don’t get how this is propaganda. It’s not suggesting that people RTO, it’s saying they should not work in bed because it will hurt their sleep. The whole “RTO” part of this was spin put on it by the submitter. So, I guess, on second thought, maybe you are right.
