i inherited 'hr.view_employee_form' form and 'personal information' page to 'base.group_user' Group but entire fields don't appear because of field access in original model and view .
note : i added all access rights ( read ) to 'base.group_user' Group
what is the solution
<record id="hide_working_hours_for_employees" model="ir.ui.view">
<field name="name">Hide Working Hours Employees Form</field>
<field name="model">hr.employee</field>
<field name="inherit_id" ref="hr.view_employee_form"/>
<field name="arch" type="xml">
<xpath expr="//field[@name='resource_calendar_id']" position="before">
<field name="inv" invisible="True"/>
</xpath>
<xpath expr="//page[@name='personal_information']" position="attributes">
<attribute name="groups">base.group_user</attribute>
</xpath>
</field>
</record>
