Wage labor refers to a system where individuals sell their labor to employers in exchange for a salary or hourly wage. This arrangement is common in many economies, allowing workers to earn income to support themselves and their families. Wage labor can be found in various sectors, including manufacturing, services, and agriculture. In this system, the employer typically sets the terms of employment, including pay rates, working hours, and job responsibilities. Workers may have different levels of job security and benefits, depending on their contracts and the labor market conditions. Wage labor is a fundamental aspect of modern economic systems.
