The minimum rates of wages will include a basic wage each for different categories of workers and a dearness allowance which will keep on changing according to changes in consumer price index. The notification will state the basic wage only and the dearness allowance will have to be calculated by us taking in to account the type of industry and the place of working. That means, the variable dearness allowance applicable to one kind of industry, say establishment engaged in plywood manufacturing may be different from that engaged in cotton textile or hotels.
For each industry a base index would have been fixed and the DA would be an amount for each point above this base index point fixed. Accordingly, if it is notified that " Dearness allowance will have to be paid at the rate of Rs 8 for every increase in consumer price index/ cost of living index above 400 points", and the month's CPI is 750 points then the DA will be equal to Rs 2800. That is 750 minus 400 multiplied by Rs 8.
Similarly, the price index of one city will be different from another city. Therefore, CPI of city A may be 780, city B it may be 756 and so on and therefore, the DA will also differ.
