SIPTU members at the Dublin Airport Authority have rejected management proposals relating to the organisation’s pension scheme.

The union said 90% of its members at the DAA voted against the proposals aimed at resolving a dispute over the Irish Airlines Superannuation Scheme, which currently has a large deficit.

Members at the Shannon Airport Authority have also rejected the proposals.

The pension scheme is shared by workers at Aer Lingus, with shareholders of that company backing the airline’s plan to contribute €190.7m to the IASS.

The DAA’s proposal would have involved the authority putting up €72m to help offset the impact of cuts at the scheme.

SIPTU did not recommend its members accept the plan and following the vote today its pensions adviser Dermot O’Loughlin said they would write to the DAA’s chief executive to seek negotiations on the matter.
