All the settlers in your towns have jobs. A job is like a class in a role playing game. Each job has a specific role, like hauling materials, building, crafting, and fighting. As your citizens work at a job, they will gain experience and levels. Some jobs, when they meet certain prerequisites, can upgrade into entirely new jobs with new capabilities.
To assign someone a new job, you will need to craft a tool for them. For instance, the Mason can craft blocks, statues, and tools from stone, but to do it he'll need a mallet and chisel crafted by the Carpenter.
Currently implemented jobs (as of Alpha 11.0.0):
Cook : This classification allows the citizen to create more advanced meals and decor that increase moral. Then Cook's Spoon crafted by the Mason is required along with the citizen being at least a level 1 farmer.
- Blacksmith: This classification allows the citizen to smelt Ingots, craft weapons and armor that Footmen can equip, and craft the Carpenter's Saw and Trapper's Knife (needed to promote a worker to a carpenter or trapper). Promotion to Blacksmith requires a Worker and a Blacksmith's Hammer, crafted by the Mason.
- Carpenter: This classification allows the citizen to create furniture, building parts, and the tools and weapons needed to promote workers to many jobs. Promotion to Carpenter requires a Carpenter's Saw, crafted by the Blacksmith.
- Farmer: This classification allows the citizen to plant crops. In addition to being a primary source of food (in addition to animals caught by the Trapper), crops can also yield raw materials for crafting, as well as decorative flowers. Promotion to Farmer requires a Worker and a Farmer's Hoe, crafted by the Carpenter.
- Footman: This classification is the first and only currently available class of warrior. They can be equipped with armor and weapons, and are tasked with defending your settlement. Promotion to Footman requires a Worker and a Wooden Practice Sword, crafted by the Carpenter.
- Shepherd: This classification allows the citizen to domesticate wild animals and harvest them for food and materials. ("Gather sheep which spawn randomly and bring them back to your pasture.") Promotion to Shepherd requires a level 3 Trapper and a Shepherd's Crook, crafted by the Carpenter.
- Trapper: This classification allows the citizen to lay traps to catch wild game, such as rabbits, producing jerky (which the citizens can eat) and pelts (needed by the Weaver for some crafting recipes). Promotion to Trapper requires a Worker and a Trapper's Knife, forged by the Blacksmith.
- Weaver: This classification allows the citizen to make crafting materials (Bolt of Cloth, Bolt of Leather, and Spool of Thread), clothing and armor, decorations, and toys. Promotion to Weaver requires a Worker and a Weaver's Spindle, crafted by the Carpenter.
- Worker: This is the default job all citizens start with. It allows them to perform basic tasks like hauling stuff around, constructing buildings, mining, and harvesting resources, e.g. gathering berries and chopping down trees to collect wood. They cannot harvest crops, but can gather them once harvested by the Farmer.
- Mason: This classification allows the citizen to create tools, furniture, and various structures from stone. One is needed in order to forge a Blacksmith's Hammer. Promotion to Mason requires a Worker and a Mason's Hammer & Chisel, crafted by the Carpenter.
Planned for inclusion in future updates:
- Archer (currently in development, slated for release soon[ish])
- Animal Trainer
- Big Game Hunter
- Magma Smith
- Miner: This classification allows the citizen to mine and create tunnels and caves.
