Workers have different Professions, such as Planter or Smith. These Professions indicate what the Worker is particularly skilled at, which allows them to do the work more effectively than others.
In addition to the Professions, Workers are also specialized in individual Goods of their Profession. This means that a Sugar Cane Planter can perform better in all Plantations than a Smith, for example, but they are especially suited for the production of Sugar Cane.
All workers can improve their special skills (e.g. sugar cane cultivation) and learn new ones in the Academy.
In the Library, general skills (e.g. gardening) can be improved.
