Mr. Mohan is worried about the new expansion plan of
the management and is worried where the new workers would come from as he is already
finding shortage of workers for the existing job. He has requested the management not to
go for expansion immediately and look at improving and consolidating the existing set

will result in economy of scale for the products and will further increase the profitability
