Labor unions can affect the economy by bargaining for higher wages and better working conditions for workers, which can lead to increased wages for unionized workers. This can also lead to higher labor costs for employers, potentially affecting production levels and overall economic output. Additionally, labor unions can have an impact on supply and demand dynamics by negotiating for better benefits and working conditions, potentially reducing the supply of labor and increasing wages.
