Karnataka Labour Dept Did Not Receive A Single Complaint From Employees Over Wage Issues At Wistron Source: Deccan Chronicle Shivaram Hebbar, Karnatakaâs Minister of Labour Department, has insisted that the labour authorities were not apprised of problems related to wages at the Wistron facility of Apple Inc where violence broke out on the previous Saturday. âWe did not receive a single letter/notice or even a complaint about a phone call about salary payment issues at Wistron. This behaviour without even trying to contact the labour department is unpardonable. We are here to listen to their grievances. There is a grievance redressal mechanism in place,â Hebbar was quoted by Economic Times.
