Summary details of work environment reviews
| Citation | Intervention(s) | Summary of results |
| Aust and Ducki26 | Dusseldorf health circles—staff discussion groups on improving working conditions | Mixed results: sickness absence increased in the controlled study, whereas it decreased in the four uncontrolled studies. One study reported improvements in some psychosocial outcomes such as relationships with colleagues. |
| Egan et al27 | Organisational-level work reorganisation: participatory committees, control over hours of work | Participatory committee interventions that increased employee control had a consistent and positive impact on self-reported health. |
| Bambra et al28 | Task structure work reorganisation: task variety, team working, autonomous groups | Task structure interventions did not generally alter levels of employee control. However, where job control decreased (and psychosocial demands increased), self-reported mental (and sometimes physical) health appeared to get worse. |
| Bambra et al29 | Changing from an 8-h, 5-day week to a compressed working week of a 12 h/10 h, 4-day week. | Health effects were inconclusive, although there was seldom a detrimental effect. Work-life balance was often improved. |
| Bambra et al30 | Changes to the organization of shift work schedules | Switching from slow to fast shift rotation; changing from backward to forward shift rotation; and the self-scheduling of shifts were found to benefit health and work–life balance. |
| Egan et al31 | Privatisation of public utilities and industries | Higher-quality studies suggested that job insecurity and unemployment resulting from privatisation impacted adversely on mental health and on some physical health outcomes. |
| Rivara and Thompson32 | Legal regulations (increased safety regulations) to prevent falls from height in construction industry | Increased regulation, when enforced with inspections, might be associated with a decrease in fall injury rates. |
