The physical, psychological and general social atmosphere at the workplace and in an occupation as a whole, as well as the external conditions, play a considerable part in occupational psychopathology. While mental illness is rare, neurosis, especially depression, is fairly common.
If individual needs and differences are not taken into account, division of work may complicate relations among workers. Monotonous, repetitive and excessively standardized jobs are disliked, while work with automatic equipment provokes a sense of isolation. Wage rates and the basis on which wages are paid are also a source of conflict and frustration, as are inadequate communications.
