This research was conducted to evaluate the relationship between selected demographics, job mastery, and job satisfaction. A total of 6,902 participants were collected from telephone and Internet service provider BellSouth. A significant relationship was found between age and job satisfaction. Job satisfaction was also significantly correlated with years spent with the company. Significant differences were found between gender and job satisfaction, as well as between education level and job satisfaction. These results suggest that as age and number of years with the company increase, job satisfaction also increases and job satisfaction may depend on the education level of the employee. The relationship between specific demographic variables, job mastery and job satisfaction is an important factor in improving not only general employee happiness but also improving job performance. For these reasons, psychologists and employers have studied the factors that can affect employees' overall job satisfaction. For example, previous research has found a significant negative relationship between social stressors and job satisfaction (Harris, Harvey, & Kacmar, 2009). This research showed that as job-related social stressors decreased, the employee's job satisfaction increased. Although this research has been beneficial in that it implies an increase in employee job satisfaction, previous research aimed at assessing other factors affecting job satisfaction has not been as successful. Previous research evaluating the relationship between specific demographic factors and job satisfaction has been inconclusive (Scott, Swortzel, & Taylor, 2005). However, Harris et al. (2009) ...... middle of paper ...... week, so that all employees have a chance to complete the survey and the data cannot be linked to the shift the employee worked work. ResultsFrequencies were pretrained to call waiting, caller ID, Internet, and multiple lines. The results indicated that 58.40% of employees did not have multiple telephone lines and 41.60% of employees had multiple telephone lines. Similar results were found for caller ID and call waiting. The frequencies revealed that 48.40% of employees did not have caller ID and 51.6% of employees did have caller ID. The frequencies also indicated that 49.10% of employees did not have a call waiting and 50.90% had a call waiting. The most surprising information provided by the frequencies was the lack of employees with Internet access. The results indicated that only 26.10% of BellSouth employees had Internet, while 70.00% of employees did not have Internet..
