Employees seem to learn a little more about their benefits as they rise in seniority.

Researchers at Unum Group Corp., Chattanooga, Tenn., have published data supporting that conclusion in a summary of results of a recent survey of 548 “Generation Y workers,” who were ages 18 to 30, and 805 baby boomer workers, who were ages 44 to 62.

The researchers found that 68% of the Generation Y workers and 76% of the boomers said the workplace is one of their most reliable sources of benefits information.

About 52% of the Generation Y workers said they were unfamiliar with critical illness insurance, and 43% said they were unfamiliar with benefits such as supplemental health insurance and long term care insurance.

Boomers were somewhat more aware of benefits offerings, with only 44% unfamiliar with critical illness insurance, and only 27% unfamiliar with long term care insurance.
