Yes. And the strikers don't need job security??
This is what it means to have solidarity with them. You don't sell them out.
Of course it's not easy.
Why should the strikers not show solidarity with the non-strikers by stopping the strike? Or show solidarity with the health care workers by enduring difficult times for the common good?
Why do strikes always seem to be surrounded by such emotional rhetoric? To me, that's a warning sign that there's no underlying logic.
