Private-sector employment growth slowed in October, as firms added the fewest jobs in six months and Washington's partisan bickering over spending hit the labor market, payrolls processing firm Automatic Data Processing Inc. said today. MarketWatch reported that private employers added 130,000 jobs this month - the fewest since April - down from 145,000 in September, according to ADP. The broader trend also shows a weakening: Over the three months through October, the economy gained an average of 142,000 jobs per month, down from an average of 220,000 at the start of the year.
