Corridor Business Journal: Job creation among small businesses broke the 45-year record in February with a net addition of 0.52 workers per firm, according to National Federation of Independent Businesses' monthly jobs report, released Thursday. The previous record was in May 1998 at 0.51 workers per firm. The percentage of owners citing labor costs as their most important problem also hit an all-time high, with 10 percent of owners reporting labor costs as their biggest problem. Small-business owners “are doing everything they can to hold onto the employees they have, while trying to produce effectively without a full staff," NFIB President and CEO Juanita Duggan said in a release. The problem is especially acute in Iowa, the organization said. "Iowa has the lowest unemployment rate in the nation -- just 2.4 percent, according to the latest federal statistics," said Matt Everson, state director of NFIB in Iowa. "That means it's even harder for small businesses in our state to find qualified workers, and it should be the focus of Iowa's policymakers to help ease that labor shortage and super-charge the local economy."
