[Excerpt] Any economy is characterized by several different patterns of industrial relations (IR)and human resource (HR) practices at the level of the workplace. Often, the patterns of IR/HR practices of firms differ based on the nature of the industry, the nature of technology and production methods used, the specific economic circumstances facing firms, and in some cases the IR/HR philosophy of key individuals. Patterns of IR/HR practices also differ based on economic sectors, with IR/HR practices in the service sector showing differences with patterns in the manufacturing sector.
