Interesting. If people work in a food production facility and they go on strike then others may starve. This is a case where we'd need to say "Keep working" or get scabs. If people work in a clothing production facility then no one suffers if they can't get a branded wearable product, so strike away. Doubt this'll work though as we are more self-satisfiers than we are group-satisfiers. Oh, and greed, money, capitalism (never forget the real cause).
