McDonald’s Employee Turns 100 and Has No Plans to Retire: ‘To Me, It’s Just a Number’ Turning 100 may be reason enough for many to adopt a slower pace of life, but not for one Pennsylvania McDonald’s employee who became a centenarian on March 3, and really has no plans to retire from the job she loves. “I get paid. I pay my bills, and that’s good. I never had a lot of money but I always have enough,” Ruthie Shuster, who works at Irwin McDonald’s in Westmoreland County three days a week wiping tables, told WTAE. As for her milestone birthday? “To me, it’s just a number,” she said.
