Sections 501.5 through 501.7 of this part prescribe the
investigation authority conferred upon the Wage and Hour Division for
the purpose of enforcing the contractual obligations. These sections
indicate the actions which may be taken upon failure to permit or
interference with an investigation. No person shall interfere with any
employee of the Secretary who is exercising or attempting to exercise
this investigative or enforcement authority. As stated in Secs. 501.5,
501.6 and in 501.19 of this part, a civil money penalty may be assessed
for each failure to permit an investigation or interference therewith,
and other appropriate relief may be sought. In addition Wage and Hour
shall report each such occurrence to ETA and may recommend to ETA denial
of future labor certifications. The taking of any one action shall not
bar the taking of any additional action.
