According to the trade union law, after retirement, the trade union still retains its membership and continues to enjoy the corresponding rights and interests. As trade union members, retired workers can actively participate in various collective activities organized by trade unions, including but not limited to outward bound training, tourism, cultural evenings and fitness activities. These activities aim to provide a colorful social platform for retired workers and promote their communication and interaction. The trade union will also regularly organize a series of professional training and skills upgrading courses to help retired workers maintain their motivation and interest in learning. Through these activities and training, retired workers can continuously enrich their lives, maintain physical and mental health, and establish deep friendship and contact with members.
