According to the expansion and construction theory (Fredrickson, 2001), positive emotions including joy, interest, and satisfaction have the ability to expand people’s instant thoughts, including action pools and building personal resources (physical, intellectual, social). Dedicated employees often experience positive emotions (Schaufeli and Van Rhenen, 2006). Happy people are more sensitive to opportunities at work, more outgoing toward others, helpful, and more confident and optimistic (Cropanza-no & Wright, 2001). For example, Bakker and Bal (2010) show that dedicate teachers are highly rated by their superiors in terms of work performance, which indicates that dedicated employees perform well and are willing to work harder. Salanova et al. (2005) A study was conducted on each employee working in Spanish restaurants and hotels. 342 employees provided information on organizational resources, professionalism and service atmosphere, and 1,140 customers evaluated their employees’ performance and Reported on their customer loyalty. This research shows that organizational resources and work input can predict the climate of services, and in turn can predict employee performance and customer loyalty. In addition, Anthropoglot et al. (2009) conducted a diary study of employees working in Greek fast food restaurants and found that the daily work level can predict objective daily financial returns.
