it can't be libel if it's true...
That may be the case, but you are still required to demonstrate (prove) that it is true, for it not to be considered libel...
PS: These are not the only guys who pay the bare minimum wage and are seeing pilots leave! This phenomenon is being repeated all over the country, eventually someone will wake up and provide a decent lifestyle, myself and many others, are more concerned with lifestyle than shiny jets!!
