McDonald’s Corp (MCD.N) said on Thursday it laid off in July 135 employees at its U.S. headquarters and 90 corporate employees posted overseas as part of a major restructuring at the fast-food chain, which has been fighting to reverse a long sales slump. McDonald’s Chief Executive Steve Easterbrook in May announced plans cut $300 million in costs by the end of 2017 as part of a corporate reset that includes simplifying and streamlining operations to make the company more nimble in an intensely competitive market.
