The aim of this study was to examine correlates of ‘workaholism’ components (Work Involvement, Drive, Enjoyment of Work). A cross-occupational sample of 661 Norwegian employees in six different organizations completed a web-based survey measuring ‘workaholism’, basic needs satisfaction at work and personality. Needs satisfaction at work was positively related to Enjoyment of Work, and negatively to Drive. Conscientiousness was positively related to all ‘workaholism’ components; Extraversion and Openness to Work Involvement and Enjoyment of Work; and Neuroticism to Drive. Negative relations were found between Neuroticism and Enjoyment of Work, and Agreeableness and Drive. Although the associations were rather weak, the findings give reason to differentiate between enthusiastic and non-enthusiastic ‘workaholic’ characteristics, which were consistent with predictions taken from central theories on ‘workaholism’.
