Problem w/ Join... Using (...) Syntax

From
Date:
how does one apply the JOIN... USING (...) syntax when
the primary key and foreign key have different names?

JOIN t_employee USING (employee_id)

works perfect when the primary and foreign key are
both named employee_id.

however, it one is named inspector_id and the other
employee_id, it doesn't work - or at least i haven't
been able to find the appropriate syntax through
searching and trial and error.

tia...

t_inspection JOIN t_employee
ON (t_employee.employee_id = t_inspection.inspector_id)
