Final Answer:
Another factor that contributed significantly to the establishment and growth of employment-based health insurance was the post-World War II collective bargaining agreements between labor unions and employers.
Step-by-step explanation:
After World War II, labor unions became powerful advocates for better working conditions and benefits for their members. During collective bargaining negotiations, unions often negotiated for health insurance coverage as part of the employment package. Employers, in turn, found offering health insurance to be a competitive advantage in attracting and retaining a skilled workforce.
This trend further solidified the link between employment and health insurance. The collective bargaining agreements established a model where health benefits became a standard part of compensation packages for many employees, especially those covered by union agreements. Over time, this practice extended beyond unionized industries to become a widespread feature of employment across various sectors.
Therefore, the post-World War II collective bargaining agreements played a crucial role in shaping employment-based health insurance in the United States.
