If you are employed, chances are you have not heard of NUNA.

However, if you are actively seeking a job and have been doing so for a while, you are probably familiar with the phrase "No Unemployed Need Apply."

This is a standard that many businesses are adopting and simply means they will not hire an applicant who is not currently employed or has recently been laid off.

It's no secret that companies prefer not to hire workers who have gaps in their employment, as it often signals that something about the applicant is undesirable to other companies.

In fact, it's not difficult to find companies on various job boards that post their preference for candidates who are currently employed.

The question many have for this practice, however, is can companies legally do this?
