Dear Mr. Parveen Kundlu,
As far as I know there is no such amendment to Section 1 subsection (3) of the Industrial Employment (Standing Orders) Act, 1946.
Section 1 Subsection (3) reads as under :
"It applies to every industrial establishment wherein one hundred or more workmen or employed, or were employed on any day of the preceding twelve months".
Still the same is being continued.
Regards,
T.M. Rao
