The work of master's in education from the diversity, titled "Certitudes and uncertainties in the experience of the time of a teaching woman", (2016 - 2018). Understands the uncertainties of how the researcher experiences time; There are various dilemmas that emerge in relation to dwelling time. The methodology is autobiographical, because, the subject is restored in its present condition and the awareness of some problems of the time. One conclusion is that female time is just that, a time that is not theirs, that deprives them of their own femininity, of their subjectivity, becoming an object of sexual, labor interest and, at most, an apparent, dignifying maternal role : that is, time that generates uncertainty for others, little time for itself.
