A labor union and two female prison employees filed a lawsuit Tuesday accusing a U.S. civil rights agency of unlawfully halting their sexual harassment case as part of wider order to indefinitely suspend proceedings in all federal-sector class claims. The lawsuit claims that the Equal Employment Opportunity Commission has ordered an indefinite suspension of all federal-sector class complaints pending before the agency’s administrative judges, who handle discrimination complaints from federal workers in process that is different than private sector workers. The women, correctional officers at a Louisiana federal prison, have a pending complaint against the Federal Bureau of Prisons.
