The purpose of this study was to determine if it’s sufficient to reduce working hours (RWH) in order to improve health and working conditions for assistant nurses (AN), and to explore if additional interventions were required. This 23-month longitudinal, interventional, parallel group study investigated the impact of RWH among AN at elderly care facilities in Gothenburg, Sweden. Study participants worked 6-hour per day with full pay. New personnel were hired to compensate for the RWH. The finding of this study showed the consistent improved health directly relating to RWH. However, the main finding was unexpectedly something different – a finding that was quite unmentioned in previous studies. As an isolated intervention, RWH was insufficient on its own to reduce the ill effects on health from lifestyle and working conditions. RWH creating the space needed to implement additional interventions.
