Labor is probably the single largest expense of any business. According to some estimates, labor costs average about 60 percent of sales. In addition to salaries, labor costs include health insurance, paid time off, child-care benefits, tuition reimbursements, and any number of other programs designed to extrinsically motivate the work force. Many companies offer the same types of benefits across their organizations without knowing whether the benefits really motivate employees at all. In other words, companies often don’t know what return they are getting on their labor investment. The same is true where you work.
