Most U.S. employers are making changes to their vendor partnerships that provide health care and wellbeing benefits to employees, according to a survey by WTW, a leading global advisory, broking, and solutions company. The moves are an attempt to address a broader range of employee needs.

"High-performing health and wellbeing vendors are now vital to employers. They have become a critical component of competitive benefit and wellbeing programs [as well as] strategic to their portfolio," Courtney Stubblefield, a senior director at WTW, said in a statement. "However, in an effort to meet the needs of their employees and improve worker health, employers are taking a close look at the value and cost savings their vendors promise. What's more, they are ready to make changes as needed."
