Optimizing your workforce involves assigning villagers to jobs where their species receives a bonus, ensuring their needs are met, and managing their Resolve. High Resolve leads to increased productivity and Reputation gain, while low Resolve can cause villagers to abandon your settlement. Always check the 'Needs' tab for each species.
Build housing appropriate for each species, provide their preferred foods, and construct service buildings that cater to their specific desires. During the Storm season, when Hostility is high, focus on boosting Resolve through services and luxury goods. Don't be afraid to reassign villagers if a particular job isn't working out or if their Resolve is dropping too low.
