This research was conducted to evaluate the relationship between selected demographics, job mastery, and job satisfaction. The telephone and internet provider BellSouth attracted a total of 6,902 participants. A significant relationship was found between age and job satisfaction. Job satisfaction was also significantly related to the years spent in the company. Significant differences were found between gender and job satisfaction, as well as education level and job satisfaction. These findings suggest that as age and years spent with the company increase, job satisfaction also increases, and job satisfaction may depend on the employee's level of education. The Relationship Between Specific Demographic Variables, Job Mastery, and Job Satisfaction Job satisfaction is an important factor in improving not only the overall happiness of employees but also improving job performance. For these reasons, both psychologists and employers have studied the factors that can influence 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 has shown that when employment-related social stressors decrease, employee job satisfaction increases. While this research has been helpful in terms of increasing employee job satisfaction, previous research evaluating other factors that influence job satisfaction has not been as successful. Previous research evaluating the relationship between specific demographic factors and job satisfaction was inconclusive (Scott, Swortzel, & Taylor, 2005). However, Harris et al. (2009) ...... half of the document ...... week, so that all employees had the opportunity to complete the survey and that the data could not be linked to the shift the employee worked. Results Call waiting, caller ID, Internet, and multiple lines frequencies were preformed. The results indicated that 58.40% of employees no longer owned phone lines and 41.60% of employees owned multiple lines. Similar results were found for caller ID and call waiting. Frequencies revealed that 48.40% of employees did not have a caller ID and 51.6% of employees did have one. The frequencies also indicate that 49.10% of employees did not receive the call waiting and 50.90% did. The most surprising information provided by the frequencies was the lack of employees who had Internet access. The results indicated that only 26.10% of BellSouth employees had Internet, while 70.00% of employees had no Internet.
