I am not sure this has to do with British (Yorkshire?) culture or just my husband's weird family:
Everyone in my family--me, sister, brother, both parents (before they retired)--went to work five days a week. We left the house every day, went away to work all day (or all night depending on their shift) then returned. Our work was separate from our home life. While we had an idea of what everybody else's job was, we weren't really involved with the jobs of other family members. It was the same for everybody I knew in New York who had a paying job. They left home, went to work, then returned many hours later. Their work lives and home lives were separate.
Everyone in my husband's family seems to work at home, in their own business, at least part of the time, and the family's businesses are all inter-related. My husband has a part-time job as a support worker, but he spends the rest of the time working on a web design business from home. My mother-in-law also does some support work part time, but also has her own business of buying, refurbishing, and reselling houses, and taking in lodgers. Her business' website was designed, and is maintained, by my husband. My brother-in-law runs his own construction business. He works on the houses my mother-in-law refurbishes.
A little while before I got married, my mother-in-law had me help her put up some fencing around the garden of one of the houses she was fixing up, because, as she told me, I'm "part of the family now." I found that to be odd. My father worked in the post office; he never asked me to help him sort the mail.
My husband thought it was strange when I started looking for a job in Leeds. To me, hopping on a train in York and arriving in Leeds 30 minutes later is extremely natural. Not much different from my previous commute from Brooklyn to Manhattan.
I don't know if this is just my husband's family, or if people in Britain/Northern England/Yorkshire have more of a tendency to combine work and family life.
