Pretty sure it wasn’t? All sources I could find seem to indicate that average work time as fallen a lot on the pas century world-wide .
That one’s biased. It doesn’t consider reproductive labour to be labour, which is a social bias rooted in historical misogyny that devalued “women’s work”.
And even then, it should have had a spike anyway during the feminist revolution, when half the population stopped working “0” hours. It doesn’t count women who didn’t work. It only counts people currently in the workforce. It hides the fact that’s twice as many these days.
