On-the-Job Training (OJT) is a hands-on method of teaching skills and competencies needed for specific jobs within the workplace. Employees learn by performing tasks under supervision, making it practical and cost-effective. Advantages include real-time experience, immediate feedback, and increased productivity. Common types of OJT include coaching, mentoring, job rotation, and apprenticeships. This method enhances employee confidence and retention by integrating learning with actual work environments.
