I can't speak for all managers but I did some analysis on this because, when we came back from COVID, we were trying to keep the number of used offices to a minimum as they took a lot longer to daily deep clean. For me personally, over a period of about 6 weeks, I needed a private room for a sensitive conversations on at least 3 days in each of those weeks. 2 of the weeks were for all 5 days. 3-4 of the conversation were related to employee's health so probably more than a typical period. But the period didn't cover any of the usual high sensitivity events, like appraisals or comp, so it's a bit of a wash. Now that doesn't mean that I need exclusive access to an office (and I don't) but it is frequent enough that it makes an important part of my job very hard without easy access. But that all obviously depends on details as to how many people you manage, org's views on management responsibility etc.
