Any time there is an election without a secret ballot, there is no real democracy. California Teachers Association has become very bold in telling teachers what to do. If teachers are put in a position where they have to openly check a box (or refuse to check a box) on cards that are stuck in front of their noses, some of them will surely feel intimidated.
Also, it's time that the president and vice-president of CTA were elected by a secret ballot.
It's a sad comment on the education system when the powerful teachers union doesn't believe that it can rely on its own ability to convey information, and the ability of teachers to make well-reasoned decisions, in order to get teachers to vote for it.
