M/S. TATA IRON & STEEL CO. LTD. vs THE WORKMEN & ORS.

The Supreme Court upheld the validity of the Coal Mines Bonus Scheme under the Coal Mines Provident Fund and Bonus Scheme Act, 1948, specifically Section 5, which allows the Central Government to create a quasi-judicial authority to resolve disputes regarding the legality of strikes. The Court ruled that the change of rest days from Sunday to another day did not constitute a change in the conditions of service under Section 9A of the Industrial Disputes Act, 1947, thus no notice was required to be given to the workmen. The appeal was dismissed, affirming the lower courts' decisions that there was no illegal strike by the workmen.
