This document summarizes the key responsibilities and roles of supervisors at the Jamaica Library Service. Supervisors act as intermediaries between management and employees, assisting with hiring, mentoring staff, and ensuring teams have necessary resources. They also coach employees, assess performance, manage workflows, and address conflicts around production, safety, communication and more. To prevent issues, supervisors must identify root causes, find win-win solutions, encourage open communication and regular training. They are also responsible for properly scheduling human resources and facilitating an open and constructive workplace culture.
