Training can take place in several places and in several ways. Most training in hospitality organizations takes place on the job. A supervisor, manager, or already skilled employee demonstrates and explains the tasks and provides immediate instruction to the trainee. This process may or may not be efficient or effective, is likely to be nonstandard, and has the potential of passing along the bad habits or practices of the employee doing the training. In some cases, training can be accomplished by the employee through self-study. In other cases, managers may elect to use a classroom setting to present the training materials. More sophisticated approaches involve computers or other technologically advanced tools.
