Intervention
Treatment according to the Dutch national guideline on the management of employees with mental health problems by occupational physicians. This guideline focuses on four aspects of the management of mental health problems:
1. The occupational physician acknowledges the interaction between the disabled employee and his surroundings (work, personal and care)
2. A simplified classification of mental health problems is introduced, with only four categories
3. The occupational physician acts as case manager, who intervenes when recovery stagnates
4. Finally, the occupational physician may also act as care manager by counseling employees with work related problems
