G. T. LAD & ORS vs CHEMICALS & FIBRES OF INDIA LTD.

The Supreme Court held that the removal of workmen's names from the muster rolls by the company was illegal under the Industrial Disputes Act, 1947, specifically referencing Section 33A. The Court established that abandonment of service requires a clear intention to relinquish duties, which was not present in this case as the workmen's absence was temporary due to a peaceful strike. The appeal was allowed, and the Tribunal's award was set aside, affirming the workmen's right to reinstatement.
