Answer:
The four major categories of labor are based on the general level of knowledge and skills needed to do a particular kind of job. These categories are unskilled, semiskilled, skilled and professional.
Explanation:
Unskilled labor is used to refer to a segment of the workforce associated with a limited skill set or minimal economic value for the work performed. Unskilled labor is generally characterized by a lower educational attainment, such as a high school diploma, GED or lack thereof, and typically results in smaller wages. Work that requires no specific education level or specialized experience is often available to the unskilled labor force.
Semi-Skilled labor does not require advanced training or specialized skills, but it does require more skills than an unskilled labor job. People who perform semi-skilled labor usually have more than a high-school diploma, but less than a college degree.
Skilled labor refers to highly trained, educated, or experienced segments of the workforce that can complete more complex mental or physical tasks on the job. Skilled labor is often specialized and may require a prolonged period of training and experience.
Professional labor means a service provided by a member of a profession or any person who earns wages from a specified activity.
