In the long run, the answer is simple. No one in their right mind. The very idea that recruiting operations that function like unemployment offices have a long term future is misplaced. Particularly in a market driven by generational labor shortages. In a tight labor market, jobs go in search of people.
Advertisements appear in a nest of content that interests the potential candidate.
Recruiters call into the office. Professional networks and associations produce contacts and meetings. The golf course creates opportunity. Bars facilitate introductions. Little league games, boat shows, jogging trails, PTAs, alumni associations and carpools are all more likely to produce the next assignment than the unemployment office.
