They really need to grow a pair, don't they? If we were in a "UK miners strike" environment, with mobs roaring about scabs on the picket like, I can understand this view, but this hasn't happened in Ireland in 20 years, so unless you have some information about actual intimidation happening, they would be well advised to grow up. I find it strange that you interpret "ah sure i don't want to cross a picket line" as being the result of some kind of intimidation or threats. I would interpret this as a statement of solidarity with their colleagues .
