Do you know the percent of the US private sector workforce is in a union?
Even here in Michigan the union percentage was up to 18.3% in 2011 which is only 1% higher than 2010. Still too high but the trend is downward over all. in 1989 is was 27.8%

When I was in the union we had a no strike clause which was a good thing for everyone. We were relatively low paid but had good benefits but our no strike clause kept us working while others around us were on strike.
