Isn't this "linking" of strikes with outside unions a violation of Taft-Hartley?

Good question.

I found this at http://www.hnn.us:

To the Wagner Act's list of prohibited management practices, the Taft-Hartley Act added a list of prohibited labor union practices. These practices included secondary boycotts (when a union induces employees to strike against their employer to get him or her to stop doing business with another employer with whom the real dispute exists); sympathy strikes or boycotts (attempting to compel an employer, other than one's own, to recognize or bargain with an unrecognized union--a practice anti-labor groups often called "blackmail picketing"); and jurisdictional strikes and boycotts (attempting to force an employer to give work to members of one particular union instead of another).
