The interpretation of 'Wages' continues to be debated time and again. For better clarity, the extract of the Act may be noted:
Section: 2 Definitions
In this Act, unless the context otherwise requires:
(a) "appropriate Government" means -
(q) "retirement" means termination of the service of an employee otherwise than on superannuation;
(r) "superannuation," in relation to an employee, means the attainment by the employee of such age as is fixed in the contract or conditions of service at the age on the attainment of which the employee shall vacate the employment;
(s) "wages" means all emoluments which are earned by an employee while on duty or on leave in accordance with the terms and conditions of his employment and which are paid or are payable to him in cash and includes dearness allowance but does not include any bonus, commission, house rent allowance, overtime wages, and any other allowance.
It's observed that questions arise regarding many components of emoluments as they are not common and identical across many sectors. Generally known are Basic and DA, whereas differences arise regarding various allowances and other benefits. While Sec. 8(s) clearly states exclusions, such as bonus, commission, HRA, OT, and any other allowance, it is clear that 'any other allowance' is excluded. However, disputes and differences are never-ending. Any contentious components can only be clarified by court cases. As such, it's not appropriate to pass judgment regarding what is to be included and what is to be excluded.
For example, in the case of Anglo French Textiles Ltd. Pondicherry Vs. Labour Court-Madras HC (22.7.1980) regarding 'incentive wages' paid forms part of 'Wages' for gratuity computation. There are many such cases dealing with these components.
