Unions silent on the biggest issues of our generation in healthcare?

Everyone keeps saying join the union. Great idea, I joined ASMOF 2 years ago. I've written to them on 3 occasions regarding scope creep, the first time being over a year ago and I've never heard back at all. Is this normal? Hopefully they get back to me before I'm working side-by-side with Dr X, DNP BSCABCD. Why are they completely silent on this issue and I MGs? I can understand that industrial disputes are slow, hence strikes are still in the pipeline but if they don't deal with these issues we are not going to have any bargaining power left at all. This seems totally lost on them?

I will keep paying my fees. It is a very small investment that might pay off big. But I'm not holding out for them to do anything either.
