The latest threat to the American workforce has arrived, and it’s on four hooves.

A public-employee union is up in arms over a team of blue-collar billy-goats employed to clear brush on a college campus. The union claims that by using the animals, Western Michigan University is snatching jobs away from union workers. They’re not kidding around, either—the union has filed a grievance against the university. Their complaint is a sort of inversion of Orwell’s Animal Farm motto: Two legs good, four legs ba-a-a-a-ad.
