Overview: Workforce allows human resources and personnel managers to customize the fields in the employee record and make some of the fields mandatory so that they can ensure that critical employee information is always collected and recorded in the system.
Start from: The Workforce module.
Navigate to Configuration > Employee Record.
In the list of fields, locate the field you want to define as mandatory.
In the field row, look for the Mandatory checkbox and check it.
Notes: Make sure the field is also marked as Visible and Editable so that it can be easily located and modified on the tab as needed.
If you want to create a new field for the worker's record, see Add a new field to the employee record.
