A ghost runs through the history of Chilean trade union organizations over the last forty years: the ghost of the regions (the provinces). The history of the Colegio de Profesores (hereinafter, CDP), the largest school teachers' union in Chile, is not exempt from this phenomenon. The objective of this research is to analyze two key episodes in the recent history of the CDP in 1993-1994, when the Biobío and Antofagasta regions developed strikes that strained their relationship with the National Board of Directors. As for documentary sources, magazines and newspapers of both national and regional circulation were used.
