A strike vote and a walk out are two VERY differant things. It's rare for a strike vote to end up not being in overwelming support. No big deal. BTW, 20 people is 6% to 7% of the workforce. Could it be that they felt it was easier to not vote vs voting against? Now all of a sudden the 99.23% is 93%. Not such a bragging number.
I also have little doubt that Polar will strike and a VERY large percent of their CM's will walk. A lot of new hires there at Polar? The big differance vs the last strike is, this will not be a three hour strike. It would not be surprising to see a lockout before they get to walk.
