What's the best way to argue that Canada Post Union's potential strike harms Canadians?

I had to temporarily shut down my store on another ebay like site . Anything I've ordered lately was all shipped by Canada Post .So it hurts small businesses and their customers too.It hurts people who live in remote areas that depend on mail delivered goods and communication.Hydro (and other greedy companies) will still expect payment of their bills even if they don't send them.They expect everyone to pay online.Well some people don't have a computer .What are they supposed to do?
