HOUSTON - A Texas federal judge on May 30 conditionally certified a class of Mexican restaurant workers who allege that they were not paid minimum or overtime wages, finding that requiring the employer to post a notice of the suit does not constitute compelled speech in violation of the First Amendment of the U.S. Constitution (Edgar A. Tapia Barajas, et al. v. Marco Antonio Acosta, et al., No. 11-3862, S.D. Texas; 2012 U.S. Dist. LEXIS 74716).
