On-the-job training is an important topic of human resource management. It helps develop the career of the individual and the prosperous growth of the organization. On the job training is a form of training provided at the workplace. During the training, employees are familiarized with the working environment they will become part of. Employees also get a hands-on experience using machinery, equipment, tools, materials, etc. Part of on-the-job training is to face the challenges that occur during the performance of the job. An experienced employee or a manager are executing the role of the mentor who through written, or verbal instructions and demonstrations are passing on his/her knowledge and company-specific skills to the new employee. Executing the training on at the job location, rather than the classroom, creates a stress-free environment for the employees. On-the-job training is the most popular method of training not only in the United States but in most of the developed countries, such as the United Kingdom, China, Russia, etc. Its effectiveness is based on the use of existing workplace tools, machines, documents and equipment, and the knowledge of specialists who are working in this field. On-the-job training is easy to arrange and manage and it simplifies the process of adapting to the new workplace. On-the-job training is highly used for practical tasks. It is inexpensive, and it doesn’t require special equipment that is normally used for a specific job. Upon satisfaction of completion of the training, the employer is expected to retain participants as regular employees.
