Only scabs cross the line.
I come from a union family and walked way further than I thought it would be to see sanders speak at a union hall. Worth it.
The strike that happened a week or so before the event would have had me staying home, had it extended, though. Even tho I only ever saw one single person on the picket line. Only scabs cross the line.
You certainly aren’t wrong, but.. at least in my area (and this is with state-level laws that fucking decimated union power), unions are relatively well respected by the population at large, because most of us have some experience with them (big trades area), and they are growing, rather than shrinking, despite having their legs cut off at the knee.
Despite being a super conservative and heavily gerrymandered area, our major trade unions (pipefitters, construction, metalworkers, electricians, etc.) never went away, much as the state (for the past 15 or so years) would have liked otherwise. And it’s making a big resurgence; there are tons of manufacturing plants near me and a lot of them are part of or bound by the unions (not just their workplace, but like regional unions)
I hope the trend continues! We need more collective action in our society. We need unions for non-tradespeople, and we don’t have any of those.. but at least the trade unions are unshakeable, and that’s a good gateway for the rest of us.
