Every job I’ve ever had the males worked far harder/longer than the females in the work place. The memo writer is correct: it’s due to human biology.
I agree (with some exceptions), but now is this related to biology or entitlement? Decades ago (before the politicization of gender) it seemed my female coworkers were much more motivated and capable; now I still see that with some older ones but they are the exceptions. The rest act like affirmative action hires with a sense of entitlement - they don’t believe they can be touched.
