Your best employees aren’t leaving because you don’t allow dogs in meetings or Ping-Pong tables in the break room, says Bruce Tulgan, management consultant and author of Winning the Talent Wars (Norton, $26.95). People are flooding out of traditional companies because they’re no longer traditional employees. They’re free agents, and you need to deal with free agents differently, by changing your focus from hiring employees to maintaining access to talent, by paying only for performance and by creating individual career tracks for everyone. In the end, this may be a war won by surrendering — to the idea that the days of the stable workforce are probably over.
