I'd be interested in that data - I have colleagues with wives / husbands doing union shift work - even if you are 100% gung-ho it seems to be 100% seniority based still or has that changed?

Things like UBI, higher minimum wage, reduce exempt classification loopholes etc all seem like ways that rules could change to benefit everyone.

I would LOVE to see the data that says a seniority based union system results in better retention of high performers and their continued push to perform well.
