This is the sixth installment of a blog series, “Collaboration and Employee Engagement; Ideas Whose Time Has Come, Again.” Earlier, we explored the beginnings of labor-management cooperation in the 1960s, the formation of the National Quality of Work Center (NQWC) that conceptualized collaboration between labor unions and management for shared benefit, and the early experiments that moved cooperation to become the new normal. Here in the last installment, we consider the significant evolution in leadership, management, and organizational thinking since the 60’s, the relevance for employee engagement and Labor management cooperation, and where labor and management cooperation fit in that context.
