Food services companies created nearly a third of the 96,000 new U.S. jobs in August, led by quickservice chains from established brands including Wendy's and Starbucks to new specialty players such as Chicago-based Protein Bar and Nando’s Peri-Peri. Chains are beefing up staff at existing stores as well as creating jobs at new units, in a push to boost service. "They’ve all been through the period where they cut too much labor," said consultant Malcolm Knapp. "The quality suffered, the experience suffered."
