Which of the following can be used to differentiate skilled and unskilled labour?

Education and training can be used to differentiate skilled and unskilled labour. Skilled labour requires a higher level of education, training and expertise to perform specialized tasks that require specific knowledge and skills. In contrast, unskilled labour usually requires less training and expertise and often involves manual labour or tasks that do not require specialized knowledge. Therefore, education and training are key factors in determining the level of skill required for a particular job, and can help to distinguish between skilled and unskilled labour.
