This paper analyses the changes the trade union movement has undergone since the 2019 revision of the labour law, promoted by the first left-leaning government since the 1930s. We observe that the changes in labour laws were accompanied by a policy of wage recovery that reversed the prolonged wage decline that had prevailed during more than thirty years of neoliberalism in Mexico. Along with the wage recovery, there has been an increase inunionisation rates, a slight growth in strikes, and the formation of new independent unions that have managed to challenge the large workers’ federations aligned to the former ruling party, and in some important cases displace them, as happened at General Motors in Silao, Guanajuato on 3 November, 2021.
