Final answer:
Unions prefer an increased demand for labor, often Support higher wages to achieve this, and may support or oppose technological advancements depending on job security negotiations. They also back laws protecting workers' rights, but some laws ironically reduce the perceived need for union membership.
Step-by-step explanation:
The question is asking about the preferences of labor unions regarding the demand for labor and what actions they might support to achieve their goals. Unions typically prefer an increased demand for labor, as this often leads to better wages and job security for their members. To boost demand for labor, unions might support higher wages for workers, as this can stimulate spending and economic growth, potentially leading to increased demand for labor.
Additionally, unions may engage in collective bargaining and negotiations to secure better conditions and pay for their workers. It is important to note that while unions might be wary of technological advancements that could displace workers, they also can be more receptive to such changes if they believe those changes will be negotiated to protect jobs.
Unions have also played a significant role in supporting the passage of laws concerning work conditions, overtime, parental leave, and regulation of pensions. This support has been crucial in establishing labor protections; however, it has also ironically resulted in some workers feeling less need for unions because the laws themselves provide protections.
