I would hope that no-one in BMI is foolish enough to strike.
The company seems to me, as an outsider, somewhat fragile. It's strategy isn't clear, it isn't making bucketfuls of cash, and it's my guess that, if the market gets bloody this winter, it could just be one of the casualties.
And what would you be striking for? An extra 1%?
Please get real, and understand that strikes belong to the last century (notwithstanding the TGWU dinosaurs at BA), and will not do anything for you and your colleagues in the long term.
