The process of gaining new skills or knowledge, particularly in the context of adapting to economic and technological changes in the workplace. Upskilling can be achieved through traditional education, on-the-job training, or through professional development, and may include acquiring skills such as leadership and emotional intelligence in addition to more specialized technical or professional skills. Upskilling can also involve the use of emerging technologies like artificial intelligence and blockchain to enhance and deepen existing skill sets. Upskilling is different from Reskilling, which involves acquiring new skills and knowledge to transition into different jobs or fields.
