On-the-Job Training (OJT) is an effective workplace learning approach where employees build skills by performing actual job tasks under expert supervision. This hands-on method is both practical and cost-efficient, offering real-time experience, instant feedback, and improved productivity. Popular OJT methods include coaching, mentoring, job rotation, and apprenticeships. By combining learning with real work environments, OJT boosts employee confidence, enhances skill retention, and strengthens long-term career development.
