National Union of Metalworkers of South Africa and Others v Bader Bop (Pty) Ltd and Another

NUMSA, a registered trade union representing approximately 26% of the employees at Bader Bop (Pty) Ltd, sought organisational rights, including the recognition of shop stewards, under the Labour Relations Act 66 of 1995. The employer already recognised a majority union and refused to recognise NUMSA’s shop stewards or bargain with it, though it was willing to grant limited access and stop-order facilities. After conciliation at the CCMA failed, NUMSA gave notice of strike action in support of its organisational demands. The employer approached the Labour Court for an interdict, which was refused. On appeal, the Labour Appeal Court granted an interdict, holding that a minority union may not lawfully strike to demand recognition of shop stewards. NUMSA and its members sought leave to appeal to the Constitutional Court.

Leave to appeal was granted; the appeal was upheld; the order of the Labour Appeal Court interdicting the strike was set aside, and the employer’s application for an interdict was dismissed.

This case is a leading authority on the constitutional right to strike and the organisational rights of minority unions. It confirms that minority unions are not barred from using strike action to pursue organisational demands, reinforcing a generous and purposive interpretation of section 23 of the Constitution. The judgment significantly shaped South African labour law by preventing majoritarianism from being used to unduly suppress minority union activity.
