David Sirota co-author of The Enthusiastic Employee: How Companies Profit by Giving Workers What They Want (Wharton School Publishing) believes far too many managers stifle employee enthusiasm across the board by using bureaucratic or punitive techniques that should be reserved for a troublesome few. Yet his book written with Louis A. Mischkind and Michael Irwin Meltzer finds that firms where employee morale is high -- such as Intuit and Barron’s -- tend to outperform competitors. In an interview with Knowledge at Wharton Sirota talks about employees’ three basic goals how to deal with employees who are ”allergic” to work and how managers can inspire greater loyalty and productivity from their workforce.
