This bill matters because it significantly changes the rules for employers and labor unions regarding who can be hired and who can be represented in the workplace. If it becomes law, it would intensify the pressure on businesses to use federal employment verification systems, making it harder for unauthorized workers to find jobs and potentially increasing the administrative burden on employers.

For unions, it could mean they are legally barred from advocating for a segment of their current or potential members, fundamentally altering their role in protecting worker rights across the board. Voters should care because it could shift the dynamics of the American workforce, affecting labor disputes, union power, and the employment landscape for both authorized and unauthorized workers, with potential impacts on wages and employment practices in various industries.
