Congress leader Karti Chidambaram reacted to Infosys Founder Narayana Murthy's remark that he was "disappointed" when India shifted from six to five-day work week. "Working longer is meaningless...Daily life is as it is a struggle...We should...move to four-day work week. 12noon on Monday to 2pm on Friday," Chidambaram said. "Work-life balance is most important for good social order," he added.
