Final answer:
Unions advocate for higher demand for labor and often support training for workers, with the trust that union negotiations will ensure job security even with the adoption of new technologies. They also have supported laws for better working conditions, contributing to both worker protection and the perceived decline in union necessity.
Step-by-step explanation:
Unions prefer higher demand for labor, and could do so by supporting training for workers in the same field as union members.
Unions often advocate for measures that protect worker rights and job security. They provide a collective voice in negotiating terms that benefit their members, especially in the face of new technologies that could potentially displace workers. Union workers, with their stronger job market experience and training, are generally more confident in embracing new technology as they trust their union to negotiate and protect their jobs and wages. Consequently, this can lead to higher demand for labor as unions help ensure that workers are prepared and trained for the evolving job market.
Moreover, unions have played a historical role in supporting laws that improve working conditions, such as those regulating overtime, parental leave, and pensions. While these laws have made workers feel less need for unions, paradoxically contributing to their decline, they also manifest the unions' commitment to improving the labor market situation for workers.
