The purpose of this quantitative study was to examine differences in gender, age and period of employment in job satisfaction. The study also examined interaction effects between the three independent variables. The study was conducted on officials at a workplace in the steel industry in Sweden. A survey was constructed in Google forms based on five selected dimensions from Copenhagen Psychosocial Questionnaire 2 (COPSOQ 2) that measured job satisfaction. The dimensions were the overall job satisfaction with work, quality of leadership, social support from superiors, social support from colleagues and social relations. All 584 officials were invited to participate where 321 responded to the survey, which corresponds to a response rate of 55%. In the result, all dimensions were found to correlate with each other and were therefore combined into one variable, total job satisfaction. There was no significant difference in sex or age, while period of employment had a negative relationship with job satisfaction. No significant interaction effects could be distinguished.
