What you say rings a bell with me too, what I hadn't quite appreciated was the delicate nature of the legal position. The danger of the politicians becoming engaged in this and clarifying the position with an eye on their beliefs wrt the EU and EU law and interference. If not careful here the unions may end up with a law passed that clearly defines UK law's supremacy and the establishment that there is no right to strike in UK law. That would be a disaster for unions and the working man.
