To improve the flight safety, CAL has to hire qualified and experienced crews engineers and mechanics.
The most experienced and the best leave for better salaries...There is no secret . Remember :" You pay peanuts, you get monkeys..."
No need to ask local pilots to sign any unfair 20 years contract to try to keep them in the company...just increase the pay and set up a career plan with significant pay increase and pilots will stay by themselves because they will be HAPPY!
