Rotating the boss would expose people to more advice. Like switching dance partners during a dance lesson the rate of learning would increase. However, I think a boss is more like a person you go teach a dance workshop with that a person that participates in it. Maybe the intern can have a new mentor every week. But I see some obstacles doing this do experienced team members. It is already hard to find people that are both an expert at the work and a great boss. Finding multiple bosses in a team seems hard. Frequently your boss needs a long term view on your activities. Career planning, performance reviews, and performance improvement plans are multi-month affairs. Coordinating with other bosses and team also happens via social capital. Having to deal with a new persons for all other teams every month might be hard.
