Fun fact: the 8 hour work day is a rather recent concept.
Meaning, prior to that, people (on average) worked less per week. But I'm guessing it heavily depended on the person and the work demand
Imagine that: Joseph the scrib only worked 6 hours today, writing only 4 pages of this massive tome he's a part of doing.
Why 4 pages? The prep work for each page and the quills, the slow process of writing each word, and scratching out each mistake as they happen.
On the flip side, Nathaniel the local blacksmith is living in the shop all day and night because of the backlog of orders and repairs. He had to hire a couple apprentices to help and he's still behind.
Mat is a painter and he wasn't feeling it for the last week, so he's been causing havoc at the local market; putting things in the wrong booths which confuses the hell out of customers and annoys the merchants.
