From the inside, RTO feels more like a way to reclaim leverage from highly paid technical employees who have become too uppity. Summoning us back to the office is about putting us in our place - but in the social hierarchy, not physically.
I genuinely wonder if that is actually the case. Our team ( fairly technical team within a non-technical type company ) repeatedly ( edit: and successfully) pushed back against any kind of RTO ( I personally sent rather non-corporate email asking why the RTO calls if they can't even get enough desks for rotation ). I am sure bosses hate being questioned, but I don't see anyone begging to do my job. In other words, something has got to give.
I don't know what is going to happen exactly. I feel the push from bigger corps will give smaller one a "permission" to do it as well, but I know I am already doing what I can to make sure I am ready. Last time the company tried to call me back in specifically, I was lucky enough to secure current position and was able to tell them no.
That said, even today, I know I would not be able to get my job back there and I didn't burn bridges in any conventional way ( unless you consider saying no to RTO burning a bridge ).
