I think it is important to supervise your new workers and help them incorperate saftey and sanitation into their routine. For example; Explain to them that using sanitation buckets, clean bar wipes and using the handwash station, are all duties they are expected to do as part of their job. Also it is important for the manager to show the new employee how to use all the equipment saftley, and it is helpful to post signs above or around the equipment to remind the employee how to saftley operate the equipment. As manager, you should try to always be aware of how people are working in the kitchen, And help them work cleanly and saftley.
