WASHINGTON — A prominent business group filed a lawsuit Wednesday challenging government rules that require federal contractors to display posters telling workers they have a legal right to form a union.
The National Association of Manufacturers is asserting that the Labor Department regulations violate the free speech rights of employers by forcing them to promote unionization of their workforces or risk losing their federal contracts. Federal officials say the posters simply inform workers of their legal rights.
Earlier this year, a federal appeals court struck down a similar rule from the National Labor Relations Board that would have affected a much wider swath of business. Full story for BostonGlobe.com subscribers.
