According to infed, supervision is important because it allows the novice to gain knowledge, skill and commitment. Supervision is also used to motivate staff members and develop effectiveness in particular job roles.
Research has shown that effective supervision has a positive effect on workers. On the contrary, a lack of supervision can have a negative effect on workforce stability, capacity, confidence, competence and morale. It is the job of the supervisor to ensure strict control over the activities of subordinates, check on workers who may waste resources and give feedback regarding complaints, grievances and problems of subordinates to superiors. Supervisors are also important because they play a key role in maintaining group unity among workers and making sure all instructions are communicated and understood by each employee.
According to CommunityCare, the primary functions of supervision are administrative case management, reflecting on and learning from practice, personal support, professional development and mediation, in which the supervisor acts as a bridge between the individual staff member and the organization for which they wok. Supervision also helps make sure a company creates workers who are skillful, knowledgeable, clear about their roles and who are assisted in their practice by sound advice and emotional support.
