In order to create a new company Job Title, navigate to Settings > HR Setup > Jobs.
From there, click on the Add New in the top right corner.
From there, you can name the new job title and select any other defaults you would like assigned. Employee type, EEO classification, and workers comp codes are all specifics that can be assigned. Make sure to Save in the top right once completed.
Note: If you add any defaults, ensure that you always check the box for Allow Override at Employee Level or the data won't be able to be updated on an individual employee basis.
