It's a win win situation. The pilot leaves for greener pastures(now more than ever considering our degradated situation) and the company gets to replace him/her with much cheaper dudes in the future. Personnally I think training costs are negligible for Cx, so having a guy working here too long is more of a cost than an asset for them,forget investment,so believe me guys , resigning Pilots is company laughing.
