Would a person cease to be a workman if owners asked subordinate to sign correspondence or because he has signed some routine documents?

In small undertakings, it is not possible to have different categories of employees like a workman, supervisor, manager, etc. A person may function as a store officer also doing the work of a storekeeper as well as a material Manager. Similarly, the personal manager may also work as a clerk filing statutory returns. Management is generally with the owner but on rare occasions, he may ask subordinates to sign correspondence. Under such a situation would a person cease to be a workman merely because he has signed some routine documents.
Warm Regards.

Dear Jagdish,

The job of a workman, in general, is repetitive in nature giving no room for taking self decisions whereas a supervisor's job is only to monitor the work of the workmen under his control to ensure whether it is carried out as per the predetermined standards of quality, quantity and time frame and out of his better expertise combined with experience to guide them then and there by sorting out occasional technical blips.

The manager's job involves the spectrum of planning, organizing, staffing, controlling, evaluating and communicating upwards, downwards and horizontal so as to achieve the results pertaining to a team, operation, geographical area and the like. Thus predominantly he is doing the thinking functions to the extent of powers delegated to him.

In a small organization, clear cut distinction of work cannot be made very exactly and at times responsibilities are shared informally according to the needs of the hour. Therefore, we cannot call all such people managers or supervisors based on certain incidental activities performed.. In such a situation, we have to ascertain one's status based on the predominant activity formally assigned and performed only.
