The hole management has dug for themselves just gets deeper. Another 2 training captains have resigned this month and because of the way training captains have been abused by the roster system, and then only for a part time job, no one is interested in replacing them. Even when the realization is made that the crew need to be employed the company is talking about forming a separate company to employ them. All this demonstrates is a lack of commitment to the New Zealand market as the only benefit would be the ability to close the crewing company down without affecting the airline.
Don't go anywhere near PB until this is all sorted is the only advise I can give anyone considering it.
