The U.S. Department of Labor (Department) is making an immediate call to action to all state administrators to ensure that UI integrity is a top priority and to develop state specific strategies to bring down the UI improper payment rate. This Unemployment Insurance Program Letter (UIPL) provides information to state workforce agencies about a national strategic plan to aggressively target UI overpayment prevention and to request that all states participate in a federal-state collaboration to significantly reduce each state’s and the national UI improper payment rates.
