Don’t sign that Card! Don’t lose your freedom. Don’t fall victim to the NNOC/CNA! 
A union card is a legal document. You signature can be considered a request to unionize and if enough victims fall for the card signing trick, the union is “IN” without an election.

That’s how they got in our hospital a few years ago. We were extremely fortunate to be able to vote them out before they could stick us with a horrible contract! It wasn’t easy and the so-called “neutrality agreement” left us employees fending for ourselves for protection from the union. Don’t sign ANYTHING that is pro-union or you will fall into their trap!
