Baywatcher, you clearly display your ignorance. It is illegal to 'compel' an employee to work on a rest day under HK labour dept ordinance and as such the employer (KA) is liable to prosecution. As background information, this airline has a dismal record in the courts when it comes to dismissal of aircrew.
While you & your spineless ilk may flex at your employers whim, these two gentlemen did not, a trait so rarely found in professional aircrew these days. Cheers.
