Impersonation Laws as Union Speech Shields

State laws that criminalize or civilly enjoin 'impersonation' of unions can be written with broad 'about to engage' standards that chill third‑party communications to members. Such measures can effectively stop advocacy groups from notifying public employees of rights (Beck rights, Janus, etc.) without any documented fraud incidents. — If adopted elsewhere, these laws could become a nationwide tool for interest groups to limit competitor speech and insulate mandatory‑dues systems from external information, with major First Amendment and labor‑market consequences.
