According to one study, 70% of employers think their employees are not optimizing the value of their employee benefits.
This piece from the Daily Mail expands from that premise to make the claim that employees could essentially increase their wages by about 30% if there were to more effectively utilize all the benefits available to them in addition to maximizing the accompanying tax breaks.
The areas highlighted by the article that provide opportunities for employees to wring more value from their employee benefits packages include childcare and dependent care benefits, fertility benefits, commute/transit compensation, tuition contribution programs, and employee assistance programs (EAPs).
