The enterprise human resources department is an upgraded form of the original "personnel department" and a functional unit within the company. Its work includes human resource planning, human recruitment and distribution, employee training and promotion, employee motivation and comfort, performance management, salary management and so on. 2. Human resource consulting company belongs to. Consulting companies generally employ some senior human resource managers to provide human resource management services according to the needs of enterprises (some aspects can also provide a full set of services separately); For example, some enterprises have no human resources department, and all human resources management functions are outsourced to consulting companies. In some enterprises, the human resources department is weak in a certain function, so it may selectively outsource a single function (such as outsourcing human recruitment alone or outsourcing salary management alone).
