Hi Madhu,
My contention comes from the definition of a worker as quoted below:
(i) "workman" means any person employed in or in connection with the work of any establishment to do any skilled, semi-skilled, or unskilled manual, supervisory, technical, or clerical work for hire or reward, whether the terms of employment are express or implied, but does not include any such person:
(A) who is employed mainly in a managerial or administrative capacity; or
(B) who, being employed in a supervisory capacity, draws wages exceeding five hundred rupees per mensem or exercises, either by the nature of the duties attached to the office or by reason of the powers vested in him, functions mainly of a managerial nature; or
(C) who is an outworker, that is to say, a person to whom any articles and materials are given out by or on behalf of the principal employer to be made up, cleaned, washed, altered, ornamented, finished, repaired, adapted, or otherwise processed for sale for the purposes of the trade or business of the principal employer and the process is to be carried out either in the home of the outworker or in some other premises, not being premises under the control and management of the principal employer.
Item C refers to an outworker, that is a person who does not work within the premises controlled by the Principal Employer. It would be logical to extend the section to services also. So if it is not provided within the premises of the Principal Employer, the person would be excluded from the definition of a worker and therefore from the protection of the act.
