SATAWU, the majority union at Equity Aviation Services (Pty) Ltd, referred a wage dispute to the CCMA and, after conciliation failed, issued a strike notice expressly on behalf of its members. A strike commenced and was accepted as protected in respect of SATAWU members. Non-unionised employees (the second to sixty-fourth applicants) also participated in the strike without issuing a separate strike notice or authorising SATAWU to act on their behalf. Equity warned these employees that their participation was unlawful and later dismissed them for unauthorised absence. The dismissed employees challenged their dismissal as automatically unfair.
