DES MOINES — Members of a Senate committee clashed Thursday over legislation that would delay and reduce the unemployment benefits paid Iowans — with backers saying the changes would still keep Iowa’s program among the nation’s most generous while critics called them “cruel” and ill-timed during a pandemic.Senators on the Labor and Business Relations Committee voted 6-4 along party lines to forward to the chamber’s debate calendar Senate Study Bill 1172, a bill that would require workers to wait a week after losing their job to receive unemployment benefits.The bill also would reduce the amount paid to workers with multiple dependents and cut worker benefits from an extended 39 weeks to 26 weeks if a business closes.The measure would take effect in July 2022 to give Iowa Workforce Development time to make the mandated changes.Sen.
