Difference between Personnel and Human Resources

What is the difference between Personnel and Human Resource? Many critics argue that there is no, clear, difference between Personnel Management (PM) and Human Resource Management (HRM). That Human Resource is just a more modernised term of reference to the traditional, Personnel. However, when examined closely, there are minor yet, crucial differences between the two.
The terms of both, Human Resource and Personnel management, refer to the same function of managing workers within the work force. Personnel management was more of an operational, administrative, record-keeping function. Whereas, Human Resource is more strategically functioned and described as the newer version of Personnel.
The term Personnel Management was originally put in place as a way of referring to activities in conjunction with the workforce. These activities consisted of Administrative tasks, payroll, staffing and contractual obligations. In regards to this, Personnel were very workforce orientated. It was described as playing the role of mediators between employers and employee's. Focusing on employees and their satisfaction, rather than concentrating heavily on management, highlighting the fact that, Personnel was less focused on the objectives of the management. Personnel's job design was the division of labour, less training of workers and evolving particularly around the welfare of employee's and employer-employee relations.
Human Resource Management came around in the late 20th century, replacing the term Personnel. Over the recent decade it has become more imperative that the needs of the works are met and regarded before management. It is thought to have been referred to as more 'people-centric'. This is beneficial as a means of ensuring that, with the workers satisfaction met, the management objectives will be then maximized. It
