Supervisors spend 17 percent of their time, or nearly one day per week, overseeing poorly performing employees, according to a survey released today by Robert Half International Inc. (NYSE: RHI). Additionally, 95 percent of respondents said a poor hiring decision at least somewhat impacts the morale of the team and more than 35 percent saying morale is greatly affected.

“Bad hires are costly, not just for the drain they place on the budget but also in terms of lost morale, productivity and time,” said Harold “Max” Messmer Jr., chairman and CEO of Robert Half. “Underperforming employees also require significant attention from employers, distracting managers from business-critical initiatives and causing other team members to pick up the slack.”

The survey is based on interviews with more than 1,400 CFOs from a stratified random sample of U.S. companies with 20 or more employees.
