So far as Items 1-9 and 11 are concerned, it becomes obvious that before any such change in conditions of service of the workmen is to be effected, as a precondition for such proposed change, notice under Section 9-A has to be issued; without complying with such a precondition of notice, the proposed change would not legally come into operation. We are directly concerned with Item 10 of this Schedule. It, therefore, becomes obvious that before any rationalisation, standardisation or improvement of plant or technique is to be resorted to by any management if by such an exercise retrenchment of workmen is likely to result, then before introducing such rationalisation, standardisation or improvement of plant or technique, as the case may be, a prior notice under Section 9-A is to be issued to the workmen who can get an opportunity to show that they may not be retrenched because of the new scheme of rationalisation etc. which is in the offing and can suggest ways and means available to the management to avoid such proposed retrenchment of the workmen despite such introduction of a new scheme. Consequently, it must be held on the very wordings of Section 9-A read with Item 10 of the Fourth Schedule
