Final answer:
McGregor contributed to the Human Relations Movement through his theory of X and Y, which challenged the Taylorist approach and emphasized the importance of creating a positive work environment.
Step-by-step explanation:
McGregor, a management theorist, made a significant contribution to the Human Relations Movement through his theory of X and Y. He believed that there are two types of managers: Theory X and Theory Y managers. Theory X managers have a negative view of employees and assume they are lazy and need to be closely supervised. Theory Y managers, on the other hand, have a positive view of employees and believe that they are self-motivated and can thrive with autonomy and responsibility.
McGregor's theory challenged the predominant Taylorist approach to management in the 1950s, which focused on strict control and hierarchical structures. Instead, McGregor advocated for a more participatory and humanistic approach to management. His work emphasized the importance of creating a work environment that fosters employee motivation, engagement, and satisfaction. McGregor's ideas had a profound impact on the field of management, shaping the development of the Human Relations Movement and influencing modern management practices.
