As stated earlier, we define Boomerangs as employees who have previously resigned from an organization but are rehired at a later date. As we
will demonstrate, boomerang employment may be planned (e.g., leaving
the workforce temporarily after the birth of a child) or unplanned (e.g.,
returning from the subsequent job after discovering that the previous job
was better). This suggests that although some Boomerangs may be identified prior to leaving (e.g., those for whom a return is planned), most other
Boomerangs may only be identified after leaving (e.g., those for whom
leaving is a mistake).
