Help me finish this if you think its a nice thing to have; some jobs overlap and can be used to specialize even further if enough people are wanting jobs:
Settlement Jobs
Miller, uses wheat seeds provided by farmers and grinds them into flour; provides flour to the bakery.
Baker, uses apples and milk supplied by foragers, flour supplied by millers, honey supplied by beekeepers, raisins supplied by ?herbalists and carrots supplied by farmers; bakes flour/oven related foods to provide.
Butcher, uses meats supplied by hunters to provide sausages.
Beekeeper, collects honey and wax; supplies bakers with honey; supplies candlestick makers with wax.
Candlestick Maker, uses wax supplied by beekeepers and yarn supplied by weavers to provide candles to miners and candleabrums.
Weaver, uses wool supplied by foragers to provide yarn to candlestick makers, tailors, and bowyers; uses plant fibers supplied by farmers to provide cloth to tailors.
Tailor, uses yarn and cloth supplied by weavers to provide clothes.
Bowyer, uses plant fibers supplied by farmers, yarn supplied by weavers and branches supplied by forages to provide bows.
Forager, gathers apples and milk to supply the baker, shears sheep to provide wool to the weaver, gathers branches for fuel and to supply the bowyer, and gathers bark to supply the tanner.
Tanner, uses skins provided by hunters to dry them and make leather in tubs to supply the leatherworkers.
Leatherworker, uses leather supplied by the tanner to provide leather goods (backpacks, quivers, armors, etc).
Etc, etc. They can be detailed so everyone has a specific job or some lumped together (like letting the tailors make gauze instead of someone else called a 'doctor' or somesuch). Could also set it up as a list of 'chores,' and anyone with those skills should check up on their status and complete the jobs to keep the settlement humming along.
