prejudicially that such application may cause serious repercussion on the industry concerned and that
public interest so requires, the appropriate Government may, by notification in the Official Gazette, direct
that the provisions of the said section shall not apply or shall apply, subject to such conditions as may be
specified in the notification, to that class of industrial establishments or to that class of workmen
employed in any industrial establishment.]
