so, you are about to strike - when, Easter of course! Why then, to have maximum impact on the fare-paying (ie. wage paying public).
How long will you strike for, 2 days, then 2 days more a bit later on. Why not have an all out strike and stay out!
That way, passengers about to book will know what to do. You can then forget about T&C's as you will be picking up your P45s instead.
I am booked to fly with you around Easter. If you disrupt my arrangements, then you can be sure that I won't be using BA again.
