Eircom's workforce will be reduced by 830 workers under an agreement approved by the company's management and representatives of the Communications' Workers Union this week.
The collective agreement, seen by RTÉ's Nuacht, states that around 830 employees will leave under an incentivised exit scheme.
It is not intended that these jobs will be replaced and the staff exits will be phased over a 12-month period.
However, the profiles of the applications are focussed on an exit date of December 2013 to facilitate employees claiming Top Slicing Relief, which is to be abolished from 31 December 2013 under the Finance Bill.
Management and the CWU have agreed to put "flexibility measures" in place to enable the maximum number of early exits.
RTÉ Nuacht understands over 200 Eircom vans will be given to workers who are availing of the scheme as part of their exit package.
