Kolkata: Coal India Ltd (CIL) on Tuesday said operations were normal in all its subsidiaries as one of the central trade unions observed a protest demonstration on Monday against the Centre’s move to allow commercial mining. The four central trade unions — CITU, BMS, HMS and AITUC — had served a joint strike notice on March 14 but subsequently, they withdrew the strike which was scheduled for Monday. CITU was the lone union to head off and called for a protest day against the commercial mining.
