calypso,
And your point is...?
Suggest your friend should have gone sick when rostered with the Captain, as surely the (your friends) decision process was not impared before the flight...
Takes two to tango. One to lead, the other to follow.
A very few folks have strange ideas, and most companies have found out about these few.
Some however have super seniority, and are indeed difficult to get rid of...but are found out eventually, dead or alive.
Hopefully the latter.
Got the picture?
