If you're required to RTO and doing it you probably aren't in a position to "insist" on jack shit.
We have offices on both sides of the Channel. It means travelling, which is expensive, hard to align, and really disruptive, but since the RTO mandate I suddenly realised _how valuable_ those in person interactions were, and how much more creative we were thanks to those watercooler chats.
I'm interviewing elsewhere, so I'm having a bit of fun seeing how far I can push the malicious compliance.
