Ever since the ringgit was pegged, MAS pilots have been cheap labor compared to all other pilots worldwide.
HR is a TOTAL waste of money - they don't "resource" anything except their own employment! If MAS wanted to seriously save money, they could start by culling the dead wood in that department.
For the pilots who remain with Mana ada Sistem, be assured that on the world scene, your standards rate highly, and you don't need to worry about any interview checks/sims. Be confident, and go for the BIG money that's offering outside.
The demand for pilots is now increasing, and will continue to do so for the forseeable future.
If MAS aren't willing to pay MARKET PRICE to keep you, there are employers who are - right now!
The ball is in your court - forget about the sabre rattling and the threats. To be honest, if half a dozen of you left today it would make NO difference - the remainder would pick up the extra work.
But like a snowball, it will have an impact down the line, when they realize that the only applicants they're receiving can't find a job anywhere else, or are demanding MUCH better conditions than they were giving you.
Selamat jalan!
