The dual labor market is an economic theory that describes the division of the labor market into two segments: the primary and secondary markets. The primary market offers better job opportunities, higher wages, and more job security, often benefiting those with more education and skills, while the secondary market tends to have lower wages, less stability, and poorer working conditions, affecting marginalized groups more severely. This division often intersects with social factors like gender and race, impacting people's access to various employment opportunities.
