I think you're confusing it with the fact that we would not get any shares if WE would go on strike during this period. A cabin crew strike would have no impact on it whatsoever.
Having said that, the targets we have to hit to ever see any shares are quite... unrealistic at best. Like the previous poster I don't think we'll ever get them. As usual, a lot of bull in the press and no reporting of the small print, such as release conditions.
(and most other airlines were already charging people to pick nice seats in the aircraft, too!).
