The data used for the current study were collected from employees in three service sectors in Seoul, the capital of Korea, in 2007. Twelve five-star hotels such as Ritz-Carlton, Hilton, Sofitel, Marriott, and Hyatt, who work in the food and beverage division, participated in this study. Top-ranked family restaurants and contract-managed foodservices were chosen in terms of sales in 2006. Once the human resources manager gave permission, employees were provided with a voluntary survey and were asked by the researcher to complete the self-administered questionnaires. The completed questionnaires were sealed in envelopes to protect employee anonymity and collected by the researcher one week later. After eliminating incomplete questionnaires, a total of 788 questionnaires were obtained over the three-week period (response rate of 77.15%).
