Retrainings, also known as skill updates, refresher courses, or professional development programs, are designed to enhance an individual's knowledge and skills. These programs help individuals improve their expertise in a particular field to remain competitive in the job market. Additionally, recertification courses, training sessions, or workshops focusing on specific tasks, skills, or software applications also fall under the category. Upskilling, reskilling, and cross-skilling are some other synonyms for retraining. Upskilling is the process of acquiring new skills or upgrading existing ones. Reskilling, on the other hand, refers to the training to learn a new set of skills. Cross-skilling is the process of acquiring knowledge of a different job within the same organization.
