Most employees think more highly of employers that offer voluntary insurance benefits than those that don’t, according to a new survey.

Anthem Blue Cross and Blue Shield, the trade name of Rocky Mountain Hospital and Medical Service, Inc., Denver, published this finding in a summary of results of a national online survey of 2,500 Americans ages 18 and older. The poll was conducted in August 2010 by Taylor Nelson Sofres (TNS) U.K. Ltd., London.

Ninety percent of the survey respondents said that when considering new job offers, they favor employers offering a full range of health benefits, including voluntary. More than half (56%) of respondents flagged voluntary benefits as “very important.”

Eight in ten employees whose company offered voluntary benefits (82%) are satisfied with their offerings, the survey reported. That satisfaction fell by 30% for those whose companies failed to offer such benefits.

Among the survey’s other findings:

– 67% of respondents say their company currently offers voluntary insurance.

–Specific groups of employed Americans are more likely to report their company offers voluntary insurance, including men (71%), those located in the Northeast region of the United States (74%), workers at large companies (81%) and those with an average household income of $50,000 or more (74%).

–Educating employees about their benefits is important. Only half of workers (56%) say they are knowledgeable about the voluntary insurance products offered at their companies.

– 67% of respondents said that having their employer provide voluntary benefits would increase their productivity at work.

–The top reasons employees enroll in voluntary benefits include cost savings (54%), greater protection for their families (50%) and ease of mind (44%).
