Dear Member,
In order to calculate the Minimum Wages, the concept of NCR is not relevant. The Minimum Wages are state-oriented. Every state issues notifications regarding the updating of Minimum Wages, which can be based on industry, location, work category, etc.
However, in Delhi, the Office Boy (if he is not doing any clerical job) will fall under the "Unskilled" category, for which the current rate is Rs. 13,584/- (wef 01.04.2017).
Thank you.
