From my limited experience, core issue is that some people (a majority in some orgs) require other people to be around them to be productive/happy/whatever. And a lot of people don't have the freedom to choose where they work as options might be highly limited. So managers tend to sacrifice QoL of some workers to improve the performance of others. Sadly, it's usually those "others" that are the loudest and most dramatic, and least willing to compromise.
