Refers to the value to an employer of the on-the-job knowledge gained by long-term employees. Knowledge capital is in essence job or employer specific information on how to efficiently achieve employer objectives, ranging from simple know-how to a knowledge of the business organization itself and the broader commercial environment in which it operates. As a concept it seeks to recognize the idea that employees become more efficient and productive the longer they remain within an organization. Knowledge capital is closely related to intellectual capital and/or human capital and forms a component of both.
