Based on the principle of downsizing by subcontracting various functions of an existing company, this volume first explains what human resources out sourcing is and how it benefits a company, with assistance in making the decision to out source and in establishing a plan. The second part describes such details as choosing a vendor and communicating the out sourcing decision. The third part provides information on out sourcing specific HR functions such as staffing, employee leasing, relocation, compensation, and benefits, while the last part addresses the area of building a vendor relationship and managing it over time.
