Secondary labor markets are characterized by high turnover, uncertain employment, low wages, lack of professional development, poor training, backward technologies and a lack of trade unions.
There are two types of secondary markets, private and public:
1. Private secondary market:
Individual investors can buy and sell shares in this type of market. Investors of this type include small businesses, individuals, pension funds, and investment companies, as well as companies with common interests in family and friends.
2. Public secondary market:
Large institutional investors participate in this type of market when they buy and sell securities on stock exchanges and counter markets.

The secondary labor market is the part of the economy that includes all jobs that do not involve managing or operating infrastructure. This includes retail and service jobs, such as cashiers and waiters and waitresses. The primary labor market refers to those jobs that involve managing and operating infrastructure.

The secondary labour market refers to a segment of the workforce characterized by low-paying, unstable, and often temporary jobs with limited benefits and little to no opportunity for career advancement. These jobs typically require minimal skills or training and are often found in industries such as retail, hospitality, food services, and manual labour. Workers in the secondary labour market often face irregular hours, lack of job security, and poor working conditions. Unlike the primary labour market, which offers stable, well-paying jobs with benefits and growth potential, the secondary labour market tends to perpetuate economic inequality. This division is often linked to socioeconomic factors, education levels, and systemic barriers, making it harder for individuals in this market to transition to more stable employment.
