Yeah, I agree. I mainly mention it because the way people comment about office designs around here, you'd think it was the only factor considered. But it might also just be cathartic to talk about disdain for open plan offices.
I had some coworkers that really couldn't deal with noise or open-plan offices. For them, it's really important that they have a quiet private office. For the majority of my coworkers, they didn't care, and did just fine in an open-plan office.
I think it's one of those things where if it's important to you, it's really important to you, but it's not important to all that many people. Which would make it a good sorting filter for a job-matching website. I don't think it'd really send much of a signal to companies regarding the relative merits of each, but it sends a very strong signal to employees who care regarding which companies might be a good fit for them.
Good point. I imagine it is a similarly strong signal for employees in the same way Remote Work can be. People who want it seem to only want it and nothing else.
