The Energy Minister says the row over the terms of the deal between ESB unions and management is just a "hiccup" - which won't lead to strikes before Christmas.
The Labour Relations Commission last night announced that the dispute over the 1.6 billion euro hole in the company's pension fund has been settled - with all pensions protected and underwritten in a "defined benefit scheme".
ESB management says there will be no impact on the company's balance sheet - but the unions say that's not the case.
Energy Minister Pat Rabbitte says the disagreement is a matter for the LRC to solve.
