I wondered about that too.
But on the other hand,
(a) there are only a few dozen 600 Series flying, out of 1000+ Challengers built,
(b) they fly way fewer hours and cycles than a regional airliner, and
(c) corporate pilots don't tend to take their employers to court as it could be rather career-limiting
