I'm currently in a situation where my manager is telling me there is a noticeable change in my productivity (for the better) and she thinks I am a better overall employee when I'm remote. Those above her in the food chain however don't see it that way and are eager to re-fill the offices as quickly as possible without getting sued. As it stands she's telling me the best she can do for me is allow me to WFH 2 days a week, under the condition that those 2 days aren't consecutive.
The point I'm trying to make here is that sometimes it's not up to your direct report and you're at the mercy of decisions made by some suits you've never even met before. More fully remote opportunities are popping up on the job market though, and thats something all 3 aforementioned parties are aware of.
