The training of trade union cadres is the key path to cultivate high-quality professional trade union cadres who are loyal and clean, and plays an important role in promoting the Party's labor movement and trade unions' work. The academic construction of trade union cadre education addresses the practical needs for high-quality, multi-dimensional training of trade union cadres and can provide a strong guarantee for the scientific and professional development of training resources for trade union cadres.General Secretary Xi Jinping's important remarks on the working class and trade union work provide fundamental guidance for this scientific construction, while the rapid development of cadre education science offers essential evidence, and the long-term practice of training trade union cadres supplies practical experience. The group attribute of trade unions and the mass nature of trade union work require that the construction of trade union cadre education must highlight the characteristics of trade unions, which can be placed in the framework of the theoretical system of trade union science, and carry out the characteristic discipline construction of " trade union plus " from the perspective of cadre education. It is suggested in this study to use trade union cadre training as a cornerstone for advancing the theoretical framework of trade union cadre education studies; to promote the academic system construction through multi-level co-construction; to enhance the discourse system construction with high-quality resources; and to guide the curriculum system construction with high-level talent cultivation.
