To me; this seems more like top cover for scabs than anything else, but I do wonder if individuals might be coerced into training positions.
I’ve never heard of such a thing. My suggestion might be if this creates safety concerns it be forwarded to the CAD for investigation. In that the CAD could be placed in a fox guarding the hen house type of situation it might also be prudent to forward the concerns to the regulatory agencies of the other nations into which CX operates and request their assistance in making an unbiased investigation into the matter. As well as a determination of— given the safety and qualification concerns — whether or not the airline remains safe enough to operate within their airspace.
