Construction, Forestry, Mining and Energy Union threatens walkout in dispute with Loy Yang B owner GDF Suez About 130 workers at Loy Yang B power station are threatening to walk off the job on Friday. VICTORIANS could face power outages in the latest industrial action by the state's biggest energy union. About 130 workers at Loy Yang B power station are threatening to walk off the job on Friday unless the Construction, Forestry, Mining and Energy Union and the station owners, GDF Suez, can resolve a dispute over a new pay deal. It comes after a court ruled union members at Yallourn power station had to cease go-slow action. The order affected similar action at Loy Yang B. An Australian Energy Market Operator spokesman said there would be enough electricity in reserve to continue supply if Loy Yang B station was turned off this week, but customers could be affected if there were any other failures on the day. The CFMEU is known for causing disruptions to Victorians during its industrial disputes. Last year the union brought the CBD to a standstill for more than two weeks at its illegal picket of Grocon's Myer Emporium construction site. CFMEU secretary Greg Hardy confirmed a 24-hour energy work stoppage was planned. He said GDF Suez "is stubbornly refusing to accept one last remaining issue" in the negotiations. A GDF Suez spokesman said the stop work would shut down the station. A Fair Work Commission hearing was called last night to try to resolve the matter. CFMEU members at Loy Yang B and Yallourn coal power stations have been involved in go-slow industrial action. The output at Loy Yang B has been cut by 20 per cent for 12 hours a day since February, and at Yallourn by 35 per cent between 4pm and 6pm every afternoon since March 1. In the Victorian Supreme Court on Thursday, Justice Elizabeth Hollingworth ordered CFMEU members at Yallourn, which is run by EnergyAustralia, to stop using the manual override. The decision meant the CFMEU had to stop the go-slow order at Loy Yang B the following day. The Electrical Trades Union yesterday confirmed its members would not take part in the 24-hour stop work.
