You might have more luck if instead you asked about working remotely full-time. It's not the same if you want to go into an office, but companies are seriously thinking about their post-covid office plans.
True, that's an interesting possibility with the current trend towards remote work. With enough of a pay raise, I could solve the private office problem by just renting the office myself out-of-pocket...
