More than one-third of all employees are prepared to bolt their current employer absent an improvement in their benefits package.

So notes new research from Aflac Inc., Columbus, Ga., which published this finding in its 2012 Aflac Workforces Report. The company conducted the survey in partnership with the national polling firm Research Now.

When asked how influential a benefits package is in the decision to leave a current employer, 34% of the report’s respondents say “very influential” or “extremely influential.” And when asked what their current employer could do to keep them at their job, 49% say “improve my benefits package.”

The report reveals that nearly half (49%) of workers are at least somewhat likely to look for a new job in the next 12 months. And more than a quarter (27%) are very or extremely likely.

The report also reveals a correlation between satisfaction with benefits and job satisfaction generally.

Nearly three-quarters of workers (73%) who indicate they are extremely or very satisfied with their benefits package also say they are extremely or very satisfied with the job. This compares with 33% of workers who are dissatisfied with their benefits and are extremely or very satisfied with their job.

The report notes that workers who are offered wellness programs and take part in the programs are significantly more likely to be satisfied with the job, feel positively towards their employer and consider their well-being better protected, compared to workers who aren’t offered wellness programs.

Among employees whose employers offer voluntary benefits options, 55% say they are satisfied with benefits offerings; 60% say the benefits package meets their family needs, 67% say their employer takes care of its employees, 61% says they are taking full advantage of their benefits offerings and 70% say that a comprehensive benefits package safeguards their health and wellness.

By comparison, among employees whose employer does not offer voluntary benefits options, the people who answered as above represented 41%, 45%, 59%, 46% and 59% of respondents, respectively.
