Having been through the build up & sabre rattling of an imminent strike with my lot earlier on this year, there are a few things worth bearing in mind.
A strike is legal, as long as the build up to it is carried out within relevant employment laws, eg timescales etc.
I would expect a further round of talks & tweaking of existing offers if a strong yes vote for a strike is mandated. The amount of improvement to any offer may well relate to the % unity of the strike mandate.
It will get very heavy, with rumours of the company doing all sorts of nasty things to strikers. This seems to be already creeping into this thread, & will snowball.
Keeping pilots, engineers & others on-side will get more & more tricky
IMO, they won't suspend strikers, because after any disruption due to action, they will want to get back to a normal service asap, & to do this, they will need a full workforce.
A weak yes vote for a strike will be a tricky scenario.
Be realistic about the strength of the yes-no split, & remember that even after people have voted, a certain % will dither &/or change their mind as the harsh reality of entering industrial action as an individual gets closer.
It ain't pretty, but if you truly believe its worth fighting for......................................................... ....
