Not sure what the terms of any voluntary redundancy you may avail of are.
The most recent early retirement packages in the major Banks provided a retirement package of approx half of final annual salary plus a lump sum of slightly in excess of 100,000 ( inclusive of statutory redundancy and the maximum capital amount allowable by commuting some of your pension ) , you could then claim job seekers for 15 months + contributory OAP in due course.
The above figures are based on 35 years service and a final salary of approx €55,000.
Hope this is some help.
