Retention is the percentage of people who were on staff and remained there from the start to the end of a time period, say, a year's first quarter. Employers can track the workers in this group and extract such information as occupation, rank or age.

Retention deals with the latter. A low retention rate is similar to filling a bucket with holes in the bottom â sure, you could keep piling on to make up for it, or you could figure out what caused the holes and how you can patch them up.
