Union Women and Child Development Minister Maneka Gandhi on Wednesday hit out at business chambers, including ASSOCHAM, FICCI and CII, saying they were “non-serious” about government’s social welfare activities and termed as a “wastage of time” attending to their functions.Speaking at a seminar ‘Women at Workplace’, organised by ASSOCHAM here today, the Union minister lashed out at participating members, representing different companies, saying such functions do not yield any results as Chambers are not serious about nation-building exercises.
