“A labor union representing roofers is reversing course and calling for repeal of the federal health law, citing concerns the law will raise its cost for insuring members. Organized labor was instrumental in getting the Affordable Care Act passed in 2010, but more recently has voiced concerns that the law could lead members to lose their existing health plans. The United Union of Roofers, Waterproofers and Allied Workers is believed to be the first union to initially support the law and later call for its repeal.”
