There are some fields an employee can edit themselves as long as you enable this access in Employee permissions.
There are some other fields that even though you can't control whether they can edit the field, you can remove the field from showing at all.
Below we explain which fields you can configure access for.
Fields you can prevent an employee to edit
In Employee permissions, you can choose whether employees can amend the following fields themselves:
Date of birth
Date of birth visibility
Fields you can remove
In Global permissions there are some fields you can prevent from showing in an employees profile altogether. This can be a workaround if it is a field they can edit, but you don't want them to be able to.
