Macsteel operates within the jurisdiction of the Metal and Engineering Industry's Bargaining Council (MEIBC). On 22 May 2021, NUMSA served Macsteel with a letter to initiate plant level negotiations on various demands relating to its members' conditions of employment. Macsteel rejected the request and advised NUMSA to table its demands at industry level. On 24 June 2021, NUMSA referred a refusal to bargain dispute to the MEIBC. During conciliation on 12 July 2021, SAEFA (on behalf of Macsteel) objected to jurisdiction, arguing that NUMSA failed to comply with the MEIBC Constitution and Dispute Resolution Agreement, which required the Secretary of Council to determine whether the dispute was a plant or industry level matter and that industry matters should be negotiated at Manco level before referral. The Commissioner upheld the jurisdictional point and found the MEIBC had no jurisdiction. NUMSA rejected the jurisdictional ruling and served notice to commence a strike on 06 September 2021. Macsteel then approached the Labour Court for an order interdicting the strike.
