This isn't a pressing question, but something I've wondered about. Why do agents switch agencies? I have assumed that agents are pretty much lone wolves, managing their own client lists while sharing some resources with the agency. Maybe they share ideas and contacts and possibly manuscripts, but they don't really work on team projects in the way that lawyers do, for instance. I don't imagine that the pay is different from agency to agency, since the pay is based on their own sales. So why switch? And is it a bad sign if an agent has switched agencies a number of times?
