Eh, there’s enough overlap in the two orgs that I could see an argument of statements of the union trying to look like official tj releases. Overall, I would agree that a union shouldn’t be allowed to use a company’s logo.
That said, their logo here looks distinctly different. Basically the only similarity is the name itself, which would be absurd to bar a union of that very company from using. I hope the courts keep throwing out these appeals because it’s clearly bullshit.
