Sorry shanwick meant to say also
Assuming that the 40% of YES voters are against strike and 11% or more of the NO voters are against strike then all credibility is lost, the current offer is withdrawn and you're back to square one.
That would be one take on it , how about another take that it would send the following message -
" we are not happy with the current offer - but we are not going to screw the airline into the ground by striking either , both parties get back round the table and hammer this out"
