Unions representing federal employees have sued the U.S. Social Security Administration in Manhattan federal court, accusing the agency of using labor negotiations to “circumvent” a court order that blocked Trump administration restrictions on collective bargaining from taking effect.

In a lawsuit filed Wednesday, attorneys for local chapters of the American Federation of Government Employees said the SSA had attempted to repackage executive orders targeting federal workers and their unions as contract proposals last year, after a federal judge in the District of Columbia had struck down their key provisions.
