There is no doubt that networking is a very important activity. As stressed previously, networking is the primary type of interaction for individuals looking for a job or who are self-employed. By focusing on networking, these individuals build relationships that allow them to make progress in finding their next opportunity, whether this opportunity is a job or a sale.
Conversely, for employed business professionals, networking becomes one of many interactions that lead to some form of relationship that raises their visibility in their workplace.
The key here is that networking is not eliminated. Employed business professionals must reallocate the time and energy they are spending (or others are telling them to spend) on networking to a much broader set of activities. Business professionals must work to raise their visibility and value.
