A day after mob violence and arson at Maruti's Manesar plant claimed the life of a senior executive and left over 100 management officials hospitalized, the police on Thursday went on the offensive and sent 91 workers into judicial custody…more than 3,000 workers armed with steel rods and blunt automobile components went on the rampage in the administration block of the Manesar unit, provoked by the management's refusal to reinstate a worker, Jiya Lal, who was suspended on the grounds of 'beating up a supervisor'. The supervisor had allegedly used a castiest slur…A trust gap between the Maruti management and the new labour union is being seen as one of the major reasons behind tensions reaching a flashpoint.
