Stay-at-home policies due to the Covid-19 pandemic have drastically increased housework and childcare. During the lockdown, couples were harshly challenged by this novel situation which could notably redistribute roles and/or could also lead to intrahousehold conflicts. In this paper, we use individual data collected from an online survey on French partnered women during the confinement of the 2020 Spring to investigate the lockdown’s effects on the household chores allocation and tensions in the couple. We show that the lockdown did not offer an opportunity to strongly renegotiate the housework and childcare division between the partners, as women still did the lion’s share during this period. Men only changed their participation in household chores when they became a ”quasi-leisure” because of the pandemic (as for shopping or playing with child). We also document that an unbalanced division of the increased household chores during the lockdown, in particular on cleaning and childcare, is directly linked to an increase of the intrahousehold conflicts. To conclude, this period did not structurally affect gender roles and stereotypes at home, despite minor intrahousehold changes.
