Cognitive labor or the third shift [1] is sociological and feminist concept referring to the invisible mental work many women do in relationships and families. [2] It is related to invisible labor, emotional labor, and unpaid work [3] while emphasizing the cost of planning, organizing, scheduling, managing and worrying, in addition to "executing." [4] [5] The distribution of cognitive labor falls disproportionately on women. [6] Handling the majority of cognitive labor is a burden that prevents women from pursuing opportunities or achieving greater health and happiness. [7] A recommendation for balancing cognitive labor is making it more explicit and visible. [8]
