Nearly 15% of employees are unaware what pension and insurance benefits their employer provides, a survey by Friends Life has found.
The results of the survey of 12, 260 adults by YouGov for Friends Life mean potentially more than 3.7m UK employees could either have benefits they're unaware of or are failing to take up protection policies they could gain.
A further survey of 3,922 adults by YouGov asked which benefits people would consider taking out through their employer with pensions life insurance, critical illness cover and income protection among the most popular answers.
The most popular to take out a financial product through an employer was contributions or subsidies from their employer, which was a motivation for 42% of 10,784 adults surveyed in a third survey.
Other popular factors included getting a better deal than is available on the high street (37.8%) and ease of access or purchase (15.2%).
Anna Spender, head of group protection proposition at Friends Life said: "It's got to come down to communication.
She added: "Employees need to know what's on offer and how it can help them. Giving them a few simple pieces of information will allow them to make more informed decisions.
"Not only are workers potentially missing out on really valuable benefits, but employers aren't getting the full value of the package they're offering. Life insurance, critical illness cover and income protection can make employees feel valued by their company and can play an important part in any staff wellness programmes.
"But if employees don't even know they're available employers aren't maximising the good will these benefits can create in staff."
