State officials adopted the package of benefit cuts and increased taxes for businesses in February, a plan designed to accelerate repayment of a $2.5 billion federal debt. Like many states, North Carolina had racked up the debt by borrowing from Washington after its unemployment fund was drained by jobless benefits during the Great Recession.

The changes go into effect Sunday for North Carolina, which has the country's fifth-worst jobless rate. The cuts on those who make unemployment claims on or after that day will disqualify the state from receiving federally funded Emergency Unemployment Compensation. That money kicks in after the state's period of unemployment compensation — now shortened from up to six months to no more than five — runs out. The EUC program is available to long-term jobless in all states. But keeping the money flowing includes a requirement that states can't cut average weekly benefits.

Because North Carolina leaders cut average weekly benefits for new claims, about 170,000 workers whose state benefits expire this year will lose more than $700 million in EUC payments, the U.S. Labor Department said.
