Article 20(1) of the declaration allows for freedom of association, so there's a positive freedom and also a negative freedom. I just mentioned the negative. The positive one is that you have the freedom to associate with an organization. If you ban workers in Hamilton in the construction field from working with the CLAC or another non-qualifying union, are you not violating their freedom of association rights?
