"Over the years, Alan Hall has made a significant contribution to this literature, especially with understandings based on research findings concerning how worker representatives act in order to deliver their roles effectively. Through the use of a mixture of theoretically informed, qualitative and quantitative methods, he, along with others, helped to establish a robust understanding of the ways in which representation and consultation on work health and safety risks and the arrangements to manage them can operate to give workers some chance that their voice may be heard. His ideas concerning "knowledge activism," for example, have been especially central to this understanding and useful in their application to a host of work situations beyond the Canadian contexts in which they were originally developed."David Walters, Cardiff University, UK
