As a BA pilot I am totally against my cabin crew colleagues going on strike. However, if that strike happens - and it happens legally - and any of my colleagues were to be sacked for going on strike, I would be first to demand that the rest of us take action to support them.
(Not married to, going out with etc etc any of them, btw!).
To be absolutely clear, I would NOT support the strike but I WOULD support anyone sacked as a result of going out on a legal strike.
