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.
This is one of those “they were so concerned with if they could do it, they didn’t stop to think if they should” sort of things.
Portable cd players were never actually that portable, because cds are just big. Minidisc players sure, but those never really caught on. MP3 players, however, caught on because they are small and easily portable, and the library doesn’t take up a binder.
