Not very likely for expat Captains. They are already upgrading locals with less time than previously required. Several of the local TREs I have talked to say they have heard nothing about lowering requirements even further. And they said the Viet training and supervisory pilots would be very much against it.
F/Os are at more risk because of the influx of cadets but nothing official yet. Just rumors.
Parc, Rishworth and DPI are negotiating new contracts with VAC this year. I believe Rishworth is the first to expire, in May.
It is pretty much expected that VAC will push for a pay cut, especially since the locals have already taken one. We'll know more in a few months.
