SIPTU has said it is extending its ballot on the Aer Lingus 2004 business plan which will see workers vote on work practice changes and get additional pay in return.
The trade union says it is still recommending that staff accept the plan.
However, in a statement, the union said it still had major concerns over the decision to put Aer Lingus on the market when the only winners would be a few 'high worth individuals and share speculators'.
'Even at this late stage there is an alarming lack of clarity on what proportion of the shareholding the State will retain, particularly in light of the Government's repeated commitments to protect vital national interests and how they in tend to protect that shareholding in future,' it added.
Yesterday, Aer Lingus published its flotation prospectus, which values the airline at up to €1.3 billion after privatisation. Shares in the company are being offered at between €2.10 and €2.70.
The Government is set to net between €190m and €293m, depending on what price the shares are actually sold. The flotation will raise around €470m after costs for Aer Lingus.
