Militant Picketing
The NLG provides a how-to on "militant picketing" at this link.
The strikers in various states are angry because, among other things, they will have to pay more out-of-pocket for their health insurance. I know A LOT of people without health insurance. Many of these people shop at Von's, Kroeger, Ralph's, Albertson's, etc. What the striker's do not realize is that the cost of health insurance will have to be borne by someone. Should the striker's get their way, the customers (many of whom are without health insurance) will be forced to pay the striker's insurance.

Most people do not understand basic economic principles, foremost being that there is no such thing as a free lunch. Henry Hazlitt makes economics accessible in this book.
