Accident, Sickness and Unemployment insurance describes what you are covered against rather than what you are actually covering. This product can be called by other titles (Mortgage Payment Protection, Loan Payment Protection or Income Protection).
There are three main types of cover:
Accident and sickness only, unemployment only and accident, sickness and unemployment combined. You can choose which is best for you, for example, your employer might provide great sick pay and so you will only be concerned with unemployment insurance. Alternatively, you might be self-employed and therefore can’t make yourself redundant, so will only want accident and sickness.
