An episode of CBS' Undercover Boss" that turned out to be a life-changing experience for sporting goods mogul Mitchell Modell first aired last November. Mitchell Modell, the CEO of the 153-store chain Modell's, shaved his head, donned an oversized walrus mustache and transformed into "Joey Glick," a worker inside the company's warehouse and at Modell's Sporting Goods locations in Washington, D.C., and Connecticut. In disguise, he drove forklifts in the warehouse, ran a cash register, and was a stock boy, sales associate and shipping clerk. The eye-opening experience of working on the front lines alongside some of his lowest paid associates changed the chain - and Modell himself - forever. "As CEO, one of the things you always wonder about is what your associates (employees) are really thinking and what their days are like. It was a great education," he said. Among the episode's most moving moments is when he gifted one of his associates with a $250,000 check when he learned she had been living in a homeless shelter with her two kids. He also suffered greatly from the physicality of the job and vowed to lose weight. On the professional side he adjusted the company's entire approach to customer service and implemented dozens of changes to increase profitability and cut red tape. "I tell everybody if you're fortunate enough to be on 'Undercover Boss' to do it in a heartbeat," he said. "If you're not fortunate enough, then go work on the front lines. It's an eye-opening experience."
