C. Method − Population and Sample
The population of this study consists of all frontline employees within the banking sector in Jordan; the total number of banks operating in Jordan is 23 banks in the end of 2009 as shown in the Table 1. According to the information obtained from the human resources managements of these banks, the total number of frontline employees was 2393. The justifications for targeting the frontline employees in this study are: first, in the service industry, production and consumption of the service are taking place at the same time. Therefore, frontline employees play a critical role to improve customers’ loyalty and profitability (Rust et al., 1996). Second, frontline employees practice higher levels of emotional tiredness than do other employees in other service organizations (Boles et al., 1997).
