BFF - That would indeed be a very noble and respectable thing to do, I would admire anyone who was able to consider the welfare of their colleagues across the industry, not just in their own company, in such a light.
My sarcastic response above was based on my understanding that Rab's post was trying to encourage individuals in another company to take part in industrial action ("this is not a time for sitting on the fence"), which is rather different than simply supporting those that choose to do so.
