I think it’s good if the phone call heavy people can find their way to phone call heavy managers, while the people who communicate well without constant phone calls can group together and work that way.

There’s a third category of people who actually need a lot of communication for different reasons (constant reassurance like you highlighted or maybe contestant management to keep them on track) but who also avoid communications like the plague. These are the hardest to manage without some rhythm of mandatory check ins.

There have been times when a founder was constantly on calls but allowed me to manage teams without them. He also continued to hold occasional calls with the team, but I wasn't present for those calls. I provided him with written progress reports. I didn't try to convince him to stop holding calls, and he didn't try to convince me that calls were mandatory. But such cases are rare.
