The point isn't to find out how people voted. That's just the only talking point management friendly forces can think of.
The point is not to pin everything on an election the company controls. Didn't you know the so-called "card check" system has ALWAYS been available to management, and has been used by companies like ATT? They don't like it because it keeps the question open instead of allowing them to go back to cheating once they've threatened, cajoled, and fired all the employees willing to stick their neck out to improve conditions and force the company to abide by federal regulations.
These employers are willing to piss away our sovereignty for cheap illegal immigrant workers; you think they blanche at eliminating anyone threatening their margins when abiding by safety regs is so expensive?
If there is no point to know how an individual voted, then why was the OPEN VOTE portion critical? I can see no reason, absolutely no reason whatsoever, to know how an individual voted unless the intent is to threaten, intimadate, maim or kill someone who disagrees with a particular point of view.
