“The principal purpose of this program was to vent grievances and address them where possible. And I think this program was as important as pay in keeping employees with us. Productivity in part is the product of tenure. That’s why I believe that turnover is the most expensive form of labor expense. I am proud that, during my thirty years at Pronto and Trader Joe’s, we had virtually no turnover of full-time employees, except for the ordinary human problems of too, too solid flesh.”
