Ask any benefits manager why their organization offers benefits to their workers, and my experience suggests that the reliably consistent answer is "to attract and retain the best workers."

Indeed, as the 2013 Health and Voluntary Workplace Benefits Survey bears out, the benefits package that an employer offers prospective employees is an important factor in their decision to accept or reject a job. In fact, a full third of employees say the benefits package is extremely important, and another 45 percent say it is very important. Moreover, a quarter of employees report they have accepted, quit, or changed jobs because of the benefits — other than salary or wage level — that an employer offered or failed to offer.

However, the WBS also found that many workers are not especially satisfied with the benefits package offered by their employer: 31 percent are only somewhat satisfied, and one-quarter are not too satisfied (12 percent) or not at all satisfied (14 percent).
