Solidarity represents 210 of the 389 cabin-crew members.
Derek Mans, Solidarity’s trade union official for aviation, said that the “ti cket ” (strike certificate) had been issued.
The union has been tr ying to negotiate with Comair since September but the dispute was ultimately referred to the Commission for Conciliation, Mediation and Arbitration (CCMA).
The CCMA ruled that Comair and Solidarity should continue negotiating, with talks being resumed on 22 January.
Last week, Comair CEO Erik Venter was unconcerned about the possibility of a strike, saying that he felt there was little support for the move. “This is a normal pressurising tactic.”
However, should the “worst-case scenario” happen, said Venter, Comair had backup staff who could pick up the slack should a small number of people go on strike.
If the numbers were significant, Venter said that fewer flights would operate. But he was sure the airline would not be grounded.
Solidarity said that Comair’s increasingly strong financial position over the past two years meant the company was in a position to be generous. In 2012 cabin crew signed a threeyear agreement forfeiting an increase in the first year as the company was battling financially. Venter took home in 2013.
