How about the following as a likely BA plan:
Court case in February, BA likely to win.
Fairly strong yes vote for a strike.
BA point out to BASSA that ballot is illegal, same reasons as before.
BA do not however go to court to prevent strike.
Strike starts some time in March, but not over easter.
BA immediately sack strikers, and anyone calling in sick.
Strike over almost before it starts.
Sacked CC take BA to tribunal for unfair dissmissal.
BA now challenge legality of strike, then contest the unfair dissmissal claims. BA may lose but the process could take years, and meanwhile, those sacked are still unemployed.
More likely:
Court case in February, BA likely to win.
However if BA lose Court case:
BA immediately issue 90-day notification of termination of contracts under SOSR to all Cabin Crew on 2nd February
BASSA in the stew and under intense pressure and likely to implode/capitulate during February (and certainly ostracise Amicus/CC89 as Satan - again)
In the meantime continue flying until 1st March (earliest strike date)
Plan 1st March schedule to operate key flights on B777 and A320 (and A318 LCY-JFK) flights during any strike
Fairly strong yes vote for a strike announced on/after 22nd February
[we are now already 30 days into 12 week strike protection period]
If it comes to a strike:
Any strikers/sickees will be noted!
Strike fails within 12 hours
BASSA denounce everyone (including their own members for liking foresight) and crawl back to lalaland to lick their wounds, never to be seen again in their current 1970's format.
BA resume normal operations and impose revised disruption agreement to not a whimper of discontent (and other contractural changes, including STR arrangements at LHR for EF)
BA announce New Fleet as previously announced as being either A320/B787and B777 or A320/A380 and B777 (remember crews can only be 'licensed' on 3 types at once) on market +10% on mixed flying and leave the dinosaurs to either continue flying the B747 + a reducing (non long range proportion of the) B777 fleet or for them to migrate to New Fleet for promotion.
Game, set and match to BA .... bye bye BASSA
