Worker strikes arent something you can legislate away unless you're going to start forcing people to work, which is, uh, let's say widely frowned upon.
If you want to end strikes, you'll need to convince workers that showing up is in their interest.
This makes strikes a rare happening, and usually very predictable.

If you're responding to my statement of "can't legislate it away", then I suppose yes you're right that is an example of being able to do that and I should have worded that differently, but the key there is that it only works if your threat convinces the workers to return. Which, according to that Wikipedia article, it didn't entirely and their staffing levels didn't fully recover for a decade.
