O.N.G.C. LTD. vs ENGINEERING MAZDOOR SANGH

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 the principle of 'last come first go' as per Section 33 of the 1947 Act. The Court affirmed the Tribunal's directive that ONGC must obtain prior permission before terminating such workers' services, thereby reinforcing protections for temporary employees.
