I think they found something to get away with their responsibilities, the company should know in the first hand that there is always that tendency that these pilots would seek greener pastures, they end up being exploited by these pilots. Before committing towards the agreed training they should furnish a very constructive work contract of let us say serve more than 5 years or more, then be asked at the fourth year if the contract be renewed or not so that they could train another pilots to do the job. This is an apparent blunder of the company side and now it cost them a lot of revenues.
