Pre-job training is for the safety and smooth handover of posts. Because, for new employees, the work content and operation process are definitely unclear and unfamiliar. Only by training first and being familiar with the work content and operation process before taking up the post can we ensure the safety of the work and operation process and smoothly hand over the post. In particular, the operation of some work lines, the working environment and workflow in the front and back of the hotel need to be trained or familiar with the class before they can work independently.
