n. insurance that is purchased by a group (such as the employees of a company) usually at a reduced rate to individual members of the group
Wikipedia
Group insurance is an insurance that covers a defined group of people, for example the members of a society or professional association, or the employees of a particular employer. Group coverage can help reduce the problem of adverse selection by creating a pool of people eligible to purchase insurance who belong to the group for reasons other than the wish to buy insurance, which might be because they are a worse than average risk.
Group insurance may offer life insurance, health insurance, and/or some other types of personal insurance.
