The following report describes a study of approaches to worker engagement in the construction industry. The study involved an extensive literature review of methods used to engage construction workers in relation to the management of health and safety on site, followed by industry consultation via workshops before developing four packages of intervention strategies to test on several sites. Before and after measures of worker perceptions combined with qualitative interviews found that three approaches successfully improve workers perceptions of worker engagement and the health and safety performance of management. Informal methods of engagement were more successful than written approaches and investment in formal health and safety training resulted in more meaningful discussions. Further research is required in relation to developing tools to measure worker engagement and the impact of foreign language speaking workers.
