"Strikes, sabotage, violent action and terrorism of every kind are not economic means. They are destructive means, designed to interrupt the movement of economic life. They are weapons of war which must inevitably lead to the destruction of society.Strikes, sabotage, violent action and terrorism of every kind are not economic means.

I think some of the operative words here are "Sabotage, violent action and terrorism". Unions in general are designed to become monopoly owners of the labor market and therefore be positioned dictate to the owners of a company their terms of employment. Their actions on the compensation issues drive up the cost of labor and dramatically reduce the profit margins of the owners and investors. Sometimes, this continues until the company is driven to the point of bankruptcy and the company closes it's doors and goes out of business.
Public sector unions, like the SEIU, attempt to strong arm the government, using the same tactics as those unions in the private sector. The problem here, of course, is the company they work for never goes out of business. The profit margins are not affected. When they government gets strong armed by the public sector unions, they simply raise taxes or print more money to pay them, which in turn is passed on to the rest of us.
They think nothing of resorting to violence whenever the regular extortion methods stop working so well for them. During the town hall meetings leading up to the vote on the Patient Protection and Affordable Care Act, a young man named Kenneth Gladny was beaten and hospitalized by members of the SEIU. Violence is the favored tool of the labor union. There are hundreds, if not thousands of examples violence associated with union activity and apparently today, my friend Dr. William Greene became another.
