The lessons imparted in Fish are very simple and provocatively empowering. The authors assert that employees in the workplace have the power to change their own attitudes about their work, creating a positive environment that will not only be more productive but happier in their lives.
Clearly, these are not novel ideas, but what gives them power is that Fish! uses as an example of this management technique the Pike Place fish market in Seattle, which is known for its lively fishmongers tossing fish to and fro. The idea is that if these workers, who have very difficult jobs that are not particularly lucrative, can maintain an amazingly motivated attitude about their work, then so can anyone.
