I love this, comedy gold:
"One or two are Union members, yes. And I don't blame them at all. It really annoys me that I'm unprotected because I don't believe in striking (unless I join the Voice which, imo, is too small to be worth the cost) Union members (I believe) have to vote on whether or not to strike. If an individual votes no but the majority vote yes then they are still expected to strike. That, imo is completely unfair"
I could just be frighteningly old-fashioned, but to me if you sign up to a union it's about solidarity, not a sort of special insurance policy. If I had your personal case (negotiating with management, taking a lot of time out of my day dealing with HR and trying to argue your corner) I expect not to see you crossing a picket line.
Looking at your argument, you're basically saying that people should get everything for nothing. You can ignore the union's democratic mandate to strike because you don't feeeeeeeel like it. You can even not belong to the union, but people like me should spend their spare time, their weekends and part of our day jobs protecting you. Is this not the very definition of entitlement?
As for calling people scum, I maintain that scabbing is bad. Doing your day job is not bad. Crossing a picket line is bad. You aren't scum if you spend your day wiping old people's bums or working to create policy or teaching classes of 30 kids. You are scum if you cross a picket line and then say "Oh well, I didn't vote for it!" or "I don't see why I should have to join a union to get representation! After all, I'm worth it!"
Hope that helps.
