Abstract: The COVID-19 pandemic crisis seriously impacted the Mexican education sector. Even though its effects cannot be calculated yet, worn out teachers are returning to classrooms after facing changes for which they were not trained and to which they had to react and adapt quickly during the long confinement. Some studies have pointed out time as a variable that ought to be highlighted. Fulfilling new job responsibilities while experiencing declines in quality of life, regardless of commuting time savings, certainly is at stake. In this paper we analyze teachers’ perceptions concerning their tasks and time use during the lockdown. A systematic review of the literature (SRL) was conducted to assess: 1) differences in time devoted to teaching practice; 2) perceptions about the use and management of time; and 3) gender differences. The results of our study validate that time directly impacted teachers’ productivity and well-being, females being the most affected.
