I am not including parents with babies or young children. Or people with older children with disabilities.
I mean people like my colleague who bounces into work saying she's really tired because she's only had 5 hours sleep. This is a one off for her, she says she sleeps well normally but we should make allowances for her today.
I would donate a limb/kidney for 5 hours sleep. Average between 3-4 hours and don't expect allowances to be made for me.
