Huh. I would have termed "emotional labor" as doing the work to maintain harmony of relationships within and outside of the home. Like being the person responsible for setting up family events, sending cards, remembering birthdays etc. Also in parenting being the more present parent. While the need to be household manager is more "mental load" like are we out of laundry soap or when is the kid's next doctor appointment. But apparently those uses aren't really accurate.
