“…An evaluation by Kompier, Gründemann, Vink, and Smulders (1996) of ten successful projects aimed at reducing sick absenteeism at work, including the project that is the subject of this study, showed that active involvement of workers during problem analysis and solution finding are important reasons for success. Vink et al (1997), when evaluating the process of the participatory project of this study, indicated that active involvement of scaffolders led to useful innovations for prioritised problems. This agrees with the findings of this study, in which management was convinced of the need for innovations and scaffolders were satisfied with the use of most of them.…”
