re: #7 wrenchwench

Is it a threat if I say to you, “Post this sign or I will never come back.”?

That isn’t what is going on.

“Failure to do so will leave us no choice but (to) do a public boycott of your business.”

The union is not saying they wont be coming back, but that they are going to do a public boycott. Again, not for what the store owner does, but for what they don’t do.

Yes, I think a lot of people are going to see this as a threat.
