“…Four interventions were focused on some form of worker welfare: Two demonstrated no effects on well-being (van den Heuvel, Demerouti, and Peeters 2015; Van Wingerden, Derks, and Bakker 2017) and two demonstrated at least one positive effect on well-being (Le Blanc et al 2007;Shonin et al 2014). For those interventions not specifically targeted at worker welfare, four demonstrated at least one positive effect on worker well-being (Cohen and Gagin 2005;Coogle, Head, and Parham 2006;Ellis, Hutman, and Chapin 2015;Glisson et al 2012) and one had no effect on well-being (Yamagishi, Kobayashi, and Nakamura 2008). Training to improve job design may be relatively cheap and relatively straightforward to implement compared to other interventions considered in this review.…”
