Labour laws/Acts & Rules are meant to be implemented in the establishments/co's/firms, shops etc as a whole whatever applicable to them depending on the status, employees strength, nature of operation etc. They are not designation centric. So far as the applicability of a particular act/law specifically defines so ie., like 'workmen' 'supervisory' 'managerial' etc only such provisions attributable to these designations would apply. And some sections are providing certain limitations on 'salary' drawn for the purposes of coverage like 'payment of wages' 'bonus' etc.
