Certainly is logical, nobody surely should expect them to recommend someone that they themselves aren’t confident are skilled enough to meet there partners expectations (airlines) be it theory or practical... that relationship would diminish fast. But for someone to say they no longer would recommend someone who does meet the criteria of theory, practical and attitude why on earth wouldn’t they recommend them?
Logic tells me as much as they may be a business and might well not go out there way to find you employment as such (especially if said student hasn’t put the effort in or done well etc) , it’s still got to be in there interests to get students out the door to a good employable standard where they hopefully find employment, if not then there business would also collapse as ultimately nobody would go there, there would be countless upset people complaining that the school was poor etc etc. and I’m just not seeing that... or am I missing something?
