Union activities refer to the organized efforts of labor unions to represent and advocate for the rights and interests of workers. These activities can include collective bargaining, where unions negotiate with employers on behalf of their members for better wages, benefits, and working conditions. Unions also engage in organizing efforts to recruit new members and raise awareness about workers' rights. Additionally, unions may participate in political activities, such as lobbying for labor-friendly legislation or endorsing candidates who support workers' rights. They often provide training and resources to help members understand their rights and improve their skills, fostering solidarity among workers in various industries.
