@FatherJackHackettsUnderpantsHamper (i don't have time space to come back to all points one by one but generally...)
I am not about to tell people what words they can and can't use. I have used scab here as shorthand talking generally (i think i may have told OP that what she has done is scab behavoiur? I can't remember exactly) and would in speech generally. I have not and would not use it to someone's face because i believe that we are each beholden to our own conscience.
Having said that: it is not on to join a union for benefits, then vote yes to strike action and then not take it. That has been done to death in this thread. I hope everyone reading has got it now.
In my personal opinion? if you're in a union you must be all in. If you vote no to strike action and the majority vote yes? you really ought to strike. There are hardship funds. I know what they cover, many of my wider family were affected by various strike actions up to and including the miners strike. I know that many families split and aren't yet reconciled. I know women who left striking husbands, and i know families that went through severe poverty all while supporting the striker. Each family / worker must make their own decision.
And if you're in the union and you break a strike? well, you are the one making that decision and must accept the consequences. Better, tbh, to leave the union over that. Non union strike breakers - I wouldn't shout scab at them but i would remember who has my back if they want favours from me (this topic also done to death on this thread. It is not bullying to cooperate and work professionally but not to do favours over and above)
Workers who don't strike/are non union get the benefits of improvements to terms and conditions in the same way they get the detriments when these get worse. It is part and parcel of living in a society with the right to join a union if you want. A win for workers, IMO, is a win for all workers.
It really is all a matter of doing the best for you and your family. That is fine (unless it is shafting your colleagues - but even then, who knows?) Joining a union "for the benefits" then voting to strike and not striking? meh.
