I agree Irish Laddie
Surely a strike is about withdrawing your labour to make a point (a point which I think is very valid) and hopefully force the upper managment into changing its ways, not about forcing your opinion on others. Your battle is not with fellow pilots, nor pilots of another airline.
It is the unions (read union members) choice to strike. Don't feel you have to bully or intimidate others, with no affiliation to the union, to join your cause.
