I've known quite a few union members who were paid out of their unions' strike funds when they went on strike. This is not so cut and dried.
I've also known hundreds of people who love their unions, from a variety of industries and walks of life (health care, service industry, trades, heavy industry.)
This is also anecdotal, of course, but it doesn't seem right to make such broad claims with a veneer of fact or universality and then add that one little caveat, "anecdotal, I know"
