The older FAs I know are as seasoned and skeptical of mgt as we are. The sentiment I've heard is that if you give the company a reason to pay you for a medical condition, you're actually giving them a medical reason to fire you (with no union job protection). I'd be curious to see how many actually took this option.
But again, why are we now comparing our labor negotiations to the FA's? They have had unilateral work rule changes implemented that we refuse to consider. Cherry-picking single items is a waste of energy.
