Despite progress toward gender equity, many women continue to take on the majority of unpaid labour within their households, including housework and child care.
On average, women spend twice as much time as men per week on housework (12.6 hours compared to 5.7) and child care (12 hours compared to 6.7).
Unpaid labour also includes cognitive labour — the mental work of anticipating household needs, identifying and weighing options to fulfil them and monitoring whether those needs have been met.
Cognitive labour underpins many physical household and child-care tasks. For example, cooking or shopping for the household requires planning meals around preferences, anticipating various needs, finding alternatives if needed and keeping track of satisfaction with meals and products.
Cognitive labour is often called the “third shift” because it’s largely mental and invisible in nature. This work is often done in the background and is dispersed throughout the day, and women in heterosexual couples tend to shoulder most of it.
As experts in organisational behaviour, we recently conducted a study that found this form of invisible labour also significantly impacts women’s workplace experiences and career outcomes, which ultimately undermines gender equity.
The hidden cost of cognitive labour
For our study, we surveyed 263 employed women and men in heterosexual relationships with employed partners across the United States and Canada. Over seven weeks from April to May 2020, participants reported weekly on the division of cognitive, household, paid and child care labour between them and their partner. They also shared their level of emotional exhaustion, turnover intentions and career resilience.
It’s worth noting that our sample was predominantly white, highly educated and included only those in heterosexual relationships, which may limit how widely these findings apply.
Our results reveal that women take on more cognitive labour than men, even when accounting for the distribution of household and paid labour. This imbalance was linked to greater emotional exhaustion, which, in turn, was associated with a higher likelihood of wanting to leave one’s job and a reduced ability to cope with workplace changes.
In addition, nearly half the participants had at least one child under the age of 18 living with them. This is notable because school and daycare closures during the early days of the COVID-19 pandemic significantly increased child care demands, which women took the brunt of.
We found mothers shouldered a disproportionate amount of child care compared to fathers. Child care — not cognitive labour — was the key predictor of emotional exhaustion, which again resulted in a reduced capacity to cope with their work environment.
In other words, women experienced higher amounts of emotional exhaustion and undermined work outcomes, but the driver varied. For women without children, it was an unequal division of cognitive labour. For mothers, it was unequal child-care responsibilities.
