How To Fix It
We learned the hard way in the USA. IT USED TO BE that you could be done in 12 days of work a month, get pay that would buy you a nice house, car, and a couple of divorces.
THEN
Disaster...things fell apart...and there is only one way back.
Be prepared to strike, be prepared to say: FLYING IS JUST A JOB...don't pay me well enough and the airline stops here. I am not in love with flying...keep saying this one over and over.
Also, change the laws in your country. In the USA, the President (an anti union guy who was a marginal air force pilot) can ORDER PILOTS back to work during a strike.
HE CAN"T ORDER the company to pay you what you are worth.
and keep saying: I AM NOT IN LOVE WITH FLYING.
And be sure to picket the Board OF Director's office.
