The Department of Homeland Security is asking a US District Court judge to narrow her ruling that prevents proposed personnel rules from being implemented. The rules have been opposed by unions representing nearly 60,000 DHS employees and were declared a violation of employee rights by Judge Rosemary M. Collyer. They would create an internal labor relations panel appointed by the DHS secretary and install a merit-based pay system. Department managers would also have increased authority over shift and duty changes.
