The Supreme Court addressed the issue of regularization of casual/contingent/temporary workmen employed by the Oil & Natural Gas Corporation Ltd. (ONGC) under the Industrial Disputes Act, 1947. The Court held that the demand for regularization of workmen who had completed 240 days of service was justified, emphasizing the need for adherence to Section 33 of the Act regarding termination of services. The Court affirmed the Tribunal's directive that ONGC must follow the principle of 'last come first go' and obtain prior permission for termination, thereby upholding the rights of the workmen.
