Some experts assert that there is no difference between human resources and personnel management. They state that the two terms can be used interchangeably, with no difference in meaning. In fact, the terms are often used interchangeably in help-wanted ads and job descriptions.

For those who recognize a difference between personnel management and human resources, the difference can be described as philosophical. Personnel management is more administrative in nature, dealing with payroll, complying with employment law, and handling related tasks. Human resources, on the other hand, is responsible for managing a workforce as one of the primary resources that contributes to the success of an organization.

When a difference between personnel management and human resources is recognized, human resources is described as much broader in scope than personnel management. Human resources is said to incorporate and develop personnel management tasks, while seeking to create and develop teams of workers for the benefit of the organization. A primary goal of human resources is to enable employees to work to a maximum level of efficiency.

Personnel management can include administrative tasks that are both traditional and routine. It can be described as reactive, providing a response to demands and concerns as they are presented. By contrast, human resources involves ongoing strategies to manage and develop an organization's workforce. It is proactive, as it involves the continuous development of functions and policies for the purposes of improving a company’s workforce.

Personnel management is often considered an independent function of an organization. Human resource management, on the other hand, tends to be an integral part of overall company function. Personnel management is typically the sole responsibility of an organization’s personnel department. With human resources, all of an organization’s managers are often involved in some manner, and a chief goal may be to have managers of various departments develop the skills necessary to handle personnel-related tasks.

As far as motivators are concerned, personnel management typically seeks to motivate employees with such things as compensation, bonuses, rewards, and the simplification of work responsibilities. From the personnel management point of view, employee satisfaction provides the motivation necessary to improve job performance. The opposite is true of human resources. Human resource management holds that improved performance leads to employee satisfaction. With human resources, work groups, effective strategies for meeting challenges, and job creativity are seen as the primary motivators.
