This article deals with the training experience performed in the home and care worker syndicate (Sindihogar) in Barcelona, by means of a collective work. For this purpose, I write a reflection joining the concept of situated knowledges (Haraway, 1995/1991) and the feminist activist research (Biglia, 2005). These concepts allowed me to lay a bridge from the reflections about knowledge and the everyday circumstances where it is produced. The first part of this work is presented as an exposition about Sindihogar. Then, the methodological section that guided the process and the implementation is explained. It concludes with some reflections related to feminist activist research to be considered.
