This study deals with the historical compromise between Labour and Capital—the so-called “Swedish model”—and the abandonment of this compromise in connection with the third industrial revolution. The focus of the study lies in the transformations in working life and labour internationalism from 1973 to 1993. The strategies of the trade union regarding the protection of workers’ rights at local, national and international levels are of particular interest. The relations between the Company Union Group at LM Ericsson, the Swedish Metalworkers’ Federation and the local union at Ericsson’s work premises in Colombia (Sintraericsson) are examined in depth. The research is conducted through archive studies and interviews according to oral history theories. The theoretical perspectives in the dissertation are mainly inspired by postcolonial and materialist world system theories. The examined relations took place in a time that from the point of view of the trade union was characterized by uncertainty and anxiety about the future. The visible effects of the technological and industrial processes of transformation in Sweden as well as in Colombia had increased, and one of the main manifestations of the changes was the decreasing demand of manual labour. The introduction of the electronic AXE-system at LM Ericsson industries constituted a significant pass toward increasingly minimized and decreasing labour-intensive telecommunication systems. In Colombia, the local management took advantage of both the political unrest and instability and the absence of functional legislation praxis of work in order to set back and, finally, repudiate Sintraericsson. Many obstacles were mounted impeding the realization of collected and vigorous international labour actions which, had these been successful, would have constituted a response to the union-hostile actions initiated by the company. The Swedish Metalworkers’ Federation and the Company Union Group at LM Ericsson in Sweden were faced with several strategical and ideological issues resulting in their support of Sintraericsson appearing as obligatory or even absent. The study further shows that LM Ericsson as a company had advantages when compared with the Labour Organizations in Sweden and Colombia. The company early established business connections in Colombia and had knowledge about, and was an active part of, the Colombian society. The company was not driven by moral principles though it on the one hand could point at Colombian laws and norms, and on the other hand at overreaching economical “laws” when it came to motivating the politics vis-à-vis the employees, the local union and the frequent dismissals of union activists at Ericsson de Colombia.
