The so called drift down started years ago when management started changing the T&Cs.
It was always going to get worse, certainly not better with regards to T&Cs. Anyone who expected the new MD/CEO to improve salaries and all the rest of it has got to have rocks in their head. Try working for any other PNG SOE or government organisation which I did when I left PX in 2011. You will very quickly learn that salaries for technically qualified (both expat and national) people within the departments isn’t a high priority on the government’s agenda to improve their workforce, hence the reason why the regulator and the AIC have struggled for decades to recruit and retain suitably qualified technical experts. The government really tries to keep the T&Cs pitched at the grassroots level and understandably so in some cases, however there should be exceptions as aviation is a global industry and not unique or specific only to PNG as we all know.
At the end of the day, everyone has s choice to remain or bail out. Horses for courses!
