(Montreal) Chorus Aviation said on Tuesday that the pilots of its subsidiary Jazz Aviation had ratified changes to their collective agreement, even as the union filed an unfair labor practice complaint against Jazz.

Jazz President Randolph deGooyer, whose company provides regional services to Air Canada, said the amended deal takes into account higher pilot salaries and expands the airline’s hiring and training options.

However, the union representing Jazz pilots, the Air Line Pilots Association (ALPA), said the deal did not enjoy overwhelming support among its members because the underlying issues did not not discussed during the negotiations.

On Monday – the same day the agreement was ratified – ALPA filed a complaint with the Canada Industrial Relations Board, claiming that Air Canada and Jazz management had violated several sections of the Canada Labor Code.

The union says the airlines failed to adhere to so-called flow agreements stipulated in the contract, which specify the number of pilots who can move directly from their work at Jazz to work at Air Canada.

Chorus clarified that the amended agreement would have no impact on its financial results.
