The aim of this study was to establish a typology of employee well-being, together with its psychosocial antecedents and consequences. Results obtained with a sample of 786 full-time employees from different occupational sectors show four types of employee well-being: 9-to-5 or relaxed, work engaged or enthusiastic, workaholic or tense, and burned-out or fatigued, each having different relationships with job and personal characteristics. This study provides evidence of a parsimonious, theory-based classification of employee well-being and contributes to the existing literature about work investment because meaningful relations were found between various types of employee well-being, and heavy and soft work investors.
