JbFly
Thats exactly what I am saying - firstly there are a lot more seconded crew than the figures you have provided.
Secondly, there are a lot of crew who are non-union members, and based on the posts on here, there are a lot of Union members who will elect to fly should a strike take place. between all of that, there will be little or no disruption.
Your source was correct in some ways ie ground staff working as crew - it was the details that were wrong
