Shifting Of Factory- Whether Attracts Sec.9A Of I D Act,1947.

Dear All Ld. members,
Plz provide your opinion on the following issue:
Whether shifting of Unit/Factory to another area within a distance of 15 km will attract section 9A of Industrial Disputes Act,1947, if other conditions of service remains unchanged. We are providing transport facility to our employees. Due to shifting of unit this transportation time will increase to another 30 minutes on one side.Whether this will be a change under shedule IV if I. D. Act,1947?
Thanks in advance for those who will give their valueable time.
Regards,
R.N. KHOLA
