The Disney Blog sums things up pretty well:
Members of the Service Trades Council approved essentially the same contract during the second vote last night. It lost by a 2% margin the first time around and won by a 6% margin this time. Translation: 47% of voters are still unhappy with the terms of the contract. That means there is likely some acrimony out there as a couple quotes in the Orlando Sentinel reveals.

Thanks for the links. We know that 47% of those who voted didn’t like the contract. That doesn’t tell us what the 70% or so who didn’t vote feel. Nor how many of the 21,000 union members will be around working for the mouse in 3 years.
