CitationIntervention(s)Summary of results
Aust and Ducki26Dusseldorf health circles—staff discussion groups on improving working conditionsMixed 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 al27Organisational-level work reorganisation: participatory committees, control over hours of workParticipatory committee interventions that increased employee control had a consistent and positive impact on self-reported health.
Bambra et al28Task structure work reorganisation: task variety, team working, autonomous groupsTask 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 al29Changing 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 al30Changes to the organization of shift work schedulesSwitching 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 al31Privatisation of public utilities and industriesHigher-quality studies suggested that job insecurity and unemployment resulting from privatisation impacted adversely on mental health and on some physical health outcomes.
Rivara and Thompson32Legal regulations (increased safety regulations) to prevent falls from height in construction industryIncreased regulation, when enforced with inspections, might be associated with a decrease in fall injury rates.
