Supervision means overseeing the subordinates at work. All managers, at whatever level, perform a supervisory function. However, at the top level of an organisation the proportion of direct supervision in each position becomes smaller and smaller than at the lower levels. This explains the reason why it is described that supervision is concerned with the first-line foremen level only. While supervising, a manager draws his attention to the day-to-day work of employees and the inter relationship among them and the groups in the organisation. Of all, the first-line supervisors play a crucial role in controlling the blue-collar workforce in the enterprise. A supervisor is an effective link between workers and management. A supervisor is directly responsible for getting the work done by the blue-collar workers and hence he becomes careful in discharging his function of issuing orders, instructions, laying down methods and procedures and guiding the people under him sincerely. Thus supervision primarily consists of instructing, guiding and inspiring human beings towards better performance which in a sense amounts to effective directing.
