Judgment has been reserved in the Labour Court matter between ArcelorMittal South Africa and the National Union of Metalworkers of South Africa.
Arcelor approached the Labour Court on an urgent basis to interdict the ongoing strike at its Coke plant.
Numsa members have downed tools over job cuts, affecting some of the companys operations in Vanderbijlpark.
The strike action follows the companys decision to retrench 107 workers ahead of Christmas.
Arcelor Mital SA argued that the mass retrenchment was covered in the collective agreement on dispute resolutions and that the workers should have opted for private mediation instead of strike action.
