In a letter to the Union Labour Department, which had demanded an explanation after the Prime Minister himself expressed concern over the violence which brought a black mark on Karnataka as an investment friendly state, the government said there was a âtechnical malfunctionâ in the system of recording employeesâ attendance which resulted in employees putting in four extra hours per day.
