The hiring process in a business is pretty clear-cut. There’s an opening that requires a certain set of skills. Qualified candidates apply, and the person deemed capable of doing the best job gets the position.
In youth sports organizations, the process can be upside-down at times. When a club needs a coach, the search begins. The club tries to get the best coach available. Adding non-coaching duties to a job description is a common way for clubs to increase the salary of quality coaches.
