Section 45(5) of the Code on Wages, 2019 permits, subject to the rules, a single application on behalf or in respect of any number of employees employed in an establishment (formerly s.16(2), Payment of Wages Act, 1936). Under section 45(4), an application may be filed by the employee concerned, by a registered Trade Union of which the employee is a member, or by the Inspector-cum-Facilitator, and trade-union membership is not a condition for a single application. Under section 45(6), the period for filing is three years from the date on which the claim arises, and a later application may be entertained on sufficient cause.
