There are many, many people out there who would continue, though. If the accident happens very quickly, almost 99.9% of the time the person doesn't notice an injury is present, and they continue playing/working/operating the same as before. During crashes, it has been shown that despite injuries, FA's continue with their job, as they are almost always in a "dazed" state.
((**to clarify an earlier point--
I said (I think, at least) in an earlier post something to the effect of: "some vision is needed to open the door", however in addition to opening the door, some vision is also neeed to see any outside obstructions that could damage the slide (and ultimately the pax. lives), they need to be able to see the manual inflation handle, and be able to pull it (used in EVERY evacuation), as well as see if the slide has completely deployed prior to allowing passengers to evacuate.**))
In any case, [surprisingly] it is not descrimination, and there is no basis for any legal procedures.
An other job you might like, EasternL1011 is this:
**Onboard supervisor** You are incharge of a large group of FA's at the domicile station, and for about 12 days out of the month (the same as a FA), you will fly around the world, supervising onboard procedures, as well as talking to the customers and getting their feedback about the airline and their alliance carriers.
