Last year, McDonald’s joined a chorus of struggling U.S. companies offering workers pay hikes to help spur a turnaround. And it looks like the move is paying off for the fast-food giant. “It has done what we expected it to — 90 day turnover rates are down, our survey scores are up — we have more staff in restaurants,” McDonald’s U.S. president Mike Andres told analysts at a UBS conference on Wednesday. “So far we’re pleased with it — it was a significant investment obviously but it’s working well.” In October, McDonald’s reported its first quarter of comparable sales gains in two years. The company built on that growth with a huge 5.7% increase in the following quarter.
