The days of lifetime employment at a single company are long gone, so business leaders today need to make an extra effort to retain talent and foster employee loyalty. Loyal employees are the heart of successful companies. When people feel fulfilled at their jobs, they go above and beyond to help the organization improve. They share expertise, resolve conflicts, suggest improvements, boost morale, help co-workers, conserve resources, and more. “Those behaviors make groups and organizations more effective — sales are better, production loss is lower, everything is better,” says Diane Bergeron, an assistant professor at Case Western’s Weatherhead School of Management in Cleveland. To become one of those lucky companies, take time to understand what your employees need and provide it for them. “As in any relationship, if you get what you need, you’re more likely to stay,” Bergeron says.
