Cross-training involves teaching an employee who was hired to perform one job function the skills required to perform other job functions. In the world of sports, the benefits of cross training are clear. By mixing different activities into a regular workout routine one can avoid overuse injuries, balance the development between muscle groups, and prevent boredom. The same may be said of cross-training in the workplace. Employees involved in cross-training programs become skilled at tasks outside the usual parameters of their jobs and thus become greater assets for the company while gaining knowledge and skills that benefit them personally.
