If I would work under worse conditions, why should I support the old guys to be more expensive to the company than myself?
Because you're not petty, because it causes no detriment to you and because you are (presumably) a pilot and inclined to side with your colleagues?
The question is why should you not? If their conditions do not cause you to be worse off, why not support them? Or is it best if they're in the gutter alongside everyone else?
