If you wish to set up more than one job role for an hourly paid employee, you can do this via the employee's staff maintenance page.
Firstly navigate to the Job Type and Pay Rates module within the employee's staff maintenance page.
Then, click the "Add New" button in the right hand corner of the page.
This will take you to the screen below where you will be able to add their other job role details (such as job title, start date, pay rate etc.).
Once you have completed the information required, click "Save" and this will add the job role to their staff maintenance page.
This will also create a secondary line on the rota for the employee, so hours can be assigned correctly for each role.
Please note that you can only add multiple job roles for hourly staff, and not salaried.
