Despite the longer time for upgrade, i think tam is still among the best choices for a job in Brazil, some may favour avianca or rio, wich for stated personal reasons might be true, and yes there are guys who quit for the others as well, but numbers. as for what i know are far from what i would call an mass exodus. I doubt the number reaches a percentage and no reason for the company to act desperately. I wish for the colleagues working there the company would improve the roster and shuttlers lifestyle as to set a higher standard for Brazilian aviators itself.
