PlasticCo is facing engagement problems among its factory workforce due to a lack of communication between managers and subordinates. Implementing Leader-Member Exchange (LMX) theory could help solve this issue. LMX focuses on the quality of relationships between leaders and members. Diagnosing these relationships through appraisals could develop trust and high-quality exchanges, improving performance. The document recommends appraisals to facilitate initial social interactions and goal-setting between managers and employees, helping transform "out-groups" into more engaged "in-groups". This provides conditions for employees to work smarter without changing shift structures.
