I think a $40B company that's willing to terminate you because you refused to polish the wings would have probably terminated you even if you were the best wing polisher ever, so might as well save the effort. In fact, if a $40B company needs its flight department to "justify" itself, I wager to say there are bigger issues happening that whether or not the wings get polished.
That being said, I'm an airline pilot with basically zero corporate experience, so...
