Don't forget that it was the Impulse pilot group that went to J* management OFFERING to fly the A320 under their current conditions (with a vague discussion of improvements).
J* management were flabergasted at the offer and fell off their chairs dumbstruck that they never could have dreamed of such a deal.
The Impulse pilot body then had no choice but to accept the deal and voted as such.
Smart management (only had to keep mouths shut), dumb pilot representatives (yet again).
J* management were preparing to START negotiations at DJ rates and would probably have paid more to secure a deal.
