"How could a family be described as hard-working unless all members are in paid employment?"
I think I'm pretty hard working, tbh. I care for DD1 who has SN, DD2 who quite probably has some SN, and DD3.
I volunteer in two primary schools. I am a Governor at two schools (parent Governor at one, Local Authority Governor at another). I sit on panels for the Independent Admissions Appeals Service and am a co-opted member of the Select Committee for Children and Young People for my LA.
My 'income' is an allowance for the Select Committee role and Carer's Allowance for caring for DD1.
Neither of those are defined as 'paid employment' so I wouldn't fit OhGoveUckYourself's definition of hard working, but I think I fulfil it in other ways.
My DH works two jobs, both part-time, but equates to full time hours. He isn't on a good salary, but his job is important to the well being and safety of children so again, I think his role is worthwhile.
Why does 'hard working' = 'earns lots'?
