This year, Church's Chicken and its sister brand, Texas Chicken, rolled out new uniforms for employees as part of its brand refresh.
"We have very low turnover, especially when we invest in the restaurants," CEO Joe Christina told Business Insider. "Throughout my career I've always seen when you invest in a restaurant, your employees feel like you're investing in them, which you are."
Christina said that new technology and updated internal practices can help in engaging customers.
"We've looked at a variety of different ways, not only our new uniforms that we'll be rolling out in the restaurants, but also our HR practices in the restaurants on how we communicate to those employees, the managers," Christina said.
"I think it's a combination of an investment in the restaurant with some of the best training out there in the restaurant business on how to keep those employees engaged, happy, and employed," he continued.
