Have you ever participated in a strike?

Grad students at UCSC are striking demanding an increase in pay to cover the high cost of living in the area (I believe the strike is also affecting UC Berkeley). I bring this up because I am also a T.A., though in light of this news I am glad I decided to leave the Bay Area for grad school. I have some sympathy for them, but will not be surprised if they are fired, as the UC president is threatening to do.

I have never participated in a strike. Have you or have you been tempted to? Do you have sympathy with strikers (in what situations)?
