Talks on a new national partnership programme have resumed today in Government buildings.
Last week broad agreement was reached between employers and trade unions over a 10 per cent pay increase over 27 months. But unions were unhappy with proposals put forward on pensions.
Unions had sought mechanisms to force employers who move to downgrade staff pension schemes to have their plans subjected to independent assessment.
Instead, the Government has proposed a number of what unions see as weaker measures.
These include the referral of disputed cases to the National Implementation Body and the establishment of a partnership group to look at pensions issues.
Ictu general secretary David Begg said Ictu was seeking to renovate the measures proposed and "make them more robust".
