A recent study in Canada has found that the quality of a woman’s relationship with their partner is impacted by inequality in the division of housework and parental responsibilities.
Generally fathers are in full-time employment and mothers in part-time employment or not at all. Statistically mothers spend far greater time than fathers doing household work, including child care. Even those mothers in full-time employment still do a far greater proportion of the housework than their partners, and particularly so when they are married and have children.
This inequality is generally explained by and linked to traditional gender role attitudes towards women and the workforce and the distribution of household chores.
Attitudes are changing however and fathers are assuming a greater parenting role. However the Canadian study shows that if a mother feels that the division of the parenting role is unfair, or that they are trapped in their parenting role, they more likely to feel dissatisfaction in the relationship overall. Specifically mothers who were employed part-time and who performed the larger share of the parenting and housework reported having the lowest relationship quality. Many women in this category felt that the pressure to meet the demands of both their employment and the home, was at the expense of the other.
The rising cost of childcare including after school care and vacation care, means that for many families’ mothers are forced to leave the work force entirely to take care of children or are forced into part-time work.
Nearly half of all divorces in Australia are among couples with children and women are more likely to file for divorce than men. 
Despite traditional views about the male breadwinner/female homemaker roles recent findings show that there is much more agreement generally between couples than ever before that the unpaid work of the home should be shared equally.
