[Notebooks on health and work: diaries of public university professors].

The main objective of this article is to present and analyze the research instrument called "health and work notebooks", focusing on the production of knowledge concerning professors' work at a public university. The notebooks serve as a qualitative and participant research technique that is appropriate for the in-depth study of relations between health and work, viewing workplaces as privileged spaces for exercising effective action in the defense of health and the work experience as the principal material for analysis. The notebooks' special quality as a research technique lies in worker's role as protagonist in the research, as the diary's author and co-participant in the study.
