Dai, trouble is the "keeping your place of employment open" is often at the cost of having someone else's place of employment shut down. One of the "successes" of the Thatcherite approach to industrial relations is by outlawing much industrial action it all too often turned groups of workers in related industries against one another, letting "the bosses" get on with their dirty work. (Excuse rather dated terminology, but it still fits.)

As for your second point. I agree with your underlying sentiment - but was stopping Hitler not a cause it was necessary to kill for (the extreme example is usually the best!). But deaths in industrial disputes aren't usually caused by workers feeling their cause is worth killing for; more situations in which feelings and tempers are running high and occasionally explode. All too often with the encouragement or even provocation of those entrusted with maintaining "law and order".
