The Hong Kong Aircrew Officers Association has filed a claim on behalf of 600 Cathay Pacific pilots to the Labour Tribunal last month accusing Cathay Pacific of short-changing them on statutory holiday pay.
This latest action follows September's Court of Final Appeal victory for cabin crew who sued Cathay for failing to give them their full statutory holiday pay.
Dennis Dolan, the association's general secretary, said the union was claiming that Cathay's formula for calculating pilots' statutory holiday pay was unsuitable. "It is not calculated properly. [The airline's] formula does not include all factors that should be considered," he told the South China Morning Post, adding that the airline was looking at a payout totalling "millions".
A Cathay spokeswoman said: "We are aware of the matter and have already had discussions with the union ... We have not received any notification from the Labour Tribunal."
