Boomerang employees, those that leave to pursue a career elsewhere before returning to a business, are becoming increasingly common in today's workplace. Once frowned upon for their frequent 'role hopping', employers are now beginning to see their value. As a former employee, they already have an understanding of your culture and industry and the experience gained from time spent in different organisations and industries can be valuable. Along with their direct business experience and insight, boomerangs often bring with them a number of valuable connections which can then be captured.
Boomerangs can be exceptionally valuable to a company's growth, there is an established employee-employer relationship that adds another layer of employee loyalty to the company, which in turn leads to increased retention. Boomerangs that have been away for a few years also have direct business value, as they bring with them new experiences, connections, points-of-view, and even potential customers.
