Looking for affordable employee training? Try approaching companies you do business with. Stephen Paliska, president of PPS Parking, in Irvine, Calif., went so far as to ask customers if he could piggyback on their training initiatives. Surprisingly, they said yes. As a result, hundreds of PPS valets have received free or inexpensive customer-service training from the likes of Marriott and Hilton, as well as from smaller customers. "We'll take it from anyone who'll give it to us. We're always looking for new training," says Paliska, who has about 350 full-time employees. He doesn't have to shell out for airfare, since most of the training workshops have been within a 15-minute drive. "We're in a very low margin business, so we have to use every cost savings," he says.
