The Union chose this route on their own , it has nothing to do with the Obama health insurance. Obviously you are unaware that the Union always looks for a way out and excuse to stop things that they can't afford and blame others for its demise. It's all about politics with them. They hurt the children not Obama.And so it begins:
“ObamaCare causes union to drop 6,000 children's health insurance coverage”
SEIU dropping coverage on its "low wage earners"
Try learning the truth on your own and not as a political view.
