Pre-job training is to introduce the rules and regulations, culture, business and employees of the enterprise to new employees. In essence, pre-job training is only the beginning of training. Training refers to the process of teaching and learning in the workplace-it teaches employees the knowledge and skills necessary to complete their work. In training, we should not only introduce new information, new technology, new skills and new procedures to employees in time, but also update their existing skills. Pre-job training may have started before new employees report for duty, so it is difficult to distinguish when pre-job training will end and when the next training will start. Employee development is a process of continuous education for employees, to be exact, it is also a necessary process that runs through the whole employment period of employees.
