Final answer:
A labor union is a group of individuals working together to achieve shared job-related goals, such as higher pay and better working conditions.
Step-by-step explanation:
A labor union is a group of individuals, working together to achieve shared job-related goals, such as higher pay, shorter working hours, greater benefits, or better working conditions. Labor unions negotiate on behalf of their members with employers to settle disputes involving pay, vacation or sick days, health care, and insurance coverage.
They seek to change the balance of power between employers and workers, operating like a monopoly in a labor market, and engage in collective bargaining to achieve their goals.
