Which module of human resources is the most difficult to do?

Admittedly, every job has its difficulties, but performance appraisal involves the evaluation and remuneration of employees' work, so it is necessary to evaluate a person and his work well. Usually, the assessment is easy to become superficial and it is very difficult to implement. Human resource planning is basically a strategic issue. It should be said that most people who do HR are just solving specific problems in their daily work, and it is rare to have strategic planning. Of course, recruitment is also difficult, especially for executives. An executive may have an impact on the life and death of the enterprise, and the difficulty can be imagined. If such a person is good at recruiting, the headhunting company will have no food. Of course, most HR only recruit general positions. After several years, people can always sum up some experience, so the difficulty is moderate. Training should be able to use the appropriate cost, and it is difficult to make up for the lack of professional skills. But generally speaking, on the one hand, China employees are very hard, and their self-study motivation is sufficient. Poor HR work affects the overall situation. On the other hand, employees often regard training as welfare and are not too picky about training. The boss thinks that the training effect is not good and does not like investment, so the importance of this job is not so great.
