The union stating, in no uncertain terms that "Bidding the 777 without a negotiated payrate is stabbing the pilot group in the back." does not institute an illegal job action. It is only a fact. It would be like stating "You should not fly while sick." This statement is not asking for pilots to call in sick, only to not fly while sick. The other statement is not asking pilots to not bid the 777, just categorizing this action.
