I had an airplane conversation with a manager at a multinational. He said they shuffled managers every couple of years. Bunch of reasons for that but partly gave the company better visibility into what's going on with a group because you have several managers on tap who've managed that group before. And if they have to fire a manager they have a number of people to tap for that role.
