There is only one field to fill in on this form but, in itself, the term Job status can be quite ambiguous.
In Natural HR, job status is a depiction of whether the employee in question is full time, part time, temporary, permanent, casual, contractor, intern or whatever other over arching description you choose to use to define individual employees and roles - the information in this field allows you to filter and group on reports so it ideally should be something informative but you can use it for anything you like.
To add or edit Job status's simply go to Administration > HR > Data management > Job Status
You can also now in addition to the content shown in the above video attach a payroll code to your job role for easier identification by your finance users. To do this select a payroll code from the drop down list using the payroll code field.
You can set up further payroll codes by going to Administration > HR > Data Management > Payroll Codes
