Studies in several national jurisdictions have highlighted the limitations of joint health and safety committees and worker representatives in affecting change in working conditions. Using Canadian data, this article focuses on the argument that many health and safety committees and worker representatives have been captured or substantially controlled through the State’s promotion of an internal responsibility system framed around a technocratic partnership. The historical development of this framing is first understood within a political economic framework which highlights several major influences, followed by a field theory analysis which explains how these control relations are established by management within workplace settings.
