I think we are going to start seeing a lot of reports about passengers being abusive towards CC on the run up to the strike. I'd also wonder about disgruntled passengers being tempted to approach picket lines to vent a bit.
The reporting that 90% voted yes will legitimize in many people's mind that most all CC should be assumed to have contributed towards their holiday woes and are legitimate targets.
On the other hand, I expect cc who show up for work despite the strike will be appreciated by the passengers quite a bit.
It will be interesting to read the reports of interactions between CC and SLF over the next couple weeks.
