Harvard Business School professor Jeffrey L. Bradach is a leading scholar on the economics and organization of the new talent market.
Many organizations undervalue the talent they have.
For some people, leaving the company is the best way to get their true market value. Examine their client and project lists, interview contractors, and meet with managers of the agency. Think about the effect on your reputation of working with the agency. However, there are some interesting models of intermediaries doing more in the area of training. For instance, Romac International, a big staffing company, has crafted a program where contractors, clients, and the agency share the costs of learning new skills.
