2930.  (a) Any employer who disciplines or discharges an employee on
the basis of a shopping investigator's report of the employee's
conduct, performance, or honesty performed by a person licensed
pursuant to Chapter 11 (commencing with Section 7500) of Division 3
of the Business and Professions Code shall provide the employee with

by one employer in connection with the affairs of only that employer
and where there exists an employer-employee relationship and the
entire investigation is conducted solely for such employer by such
licensee.
