Although four in 10 employees identify themselves as DIYers (Do-It-Yourselfers) when it comes to making financial decisions, they are falling significantly behind on prioritizing and meeting key financial goals, according to a study by the Guardian Life Insurance Co. of America.

The second annual Guardian Workplace Benefits Study found that this is especially true for millennials, who may need professional advice to achieve their financial aims.

"The majority of employees are starting to realize the true value of their workplace benefits, but a workplace benefits program doesn't work if employees drop the ball," said Phyllis Falotico, assistant vice president, Group Marketing, at Guardian.
