OSLO, March 27 (Reuters) - Close to 25,000 Norwegian private-sector workers plan to strike from April 1 unless employers agree to demands for higher wages, labour unions said on Wednesday.
There were no oil and gas producers on the list of employers, although some suppliers to the oil industry would be affected.
The Norwegian Confederation of Trade Unions (LO) threatened a strike among almost 23,000 people, while the smaller Confederation of Vocational Unions (YS) said 1,600 of its members would be part of the initial wave.
Starting on Saturday, a state mediator will try to broker a deal ahead of a deadline the following day. While smaller strikes often occur in Norway, major conflicts are rare.
Power producer Statkraft was among those that would be hit in the first wave of strikes, as were Telenor Aker Solutions, Orkla and Carlsberg, LO said.
If a strike does break out, the two unions could gradually escalate it to some 190,000 people. (Reporting by Terje Solsvik Editing by Mark Heinrich)
