Opponents of the effort to unionize thousands of Minnesota home day care operators are appealing the ruling of a federal judge who dismissed their case.
A group of day care operators filed the appeal Tuesday.
They're asking the court for an injunction of the union drive while the appeal is considered.
The plaintiffs say in their appeal that they are private business owners and that being forced to associate with a union would violate their First Amendment rights.
Judge Michael Davis wrote in his ruling last week that the opponents' lawsuit is premature.
