that's the wrong question. BALPA wouldn't - and couldn't "call for a strike". What they can do is ballot the membership and see if THEY do. The CC are the mouthpiece of the collective members wishes.
When did it happen last? Dunno, but I think Virgin are being balloted on it at the moment. Strikes are enormously expensive for both sides, and management normally either have "right" on their side, or they don't. If they don't, and expensive IA occurs which could have been avoided, then there will be v.angry shareholders to justify it to. If a lot of reasonable people think the workers are being outrageous (eg BA cabin crew?) then the managers will generally have more support for not backing down.
