AIB boss David Hodgkinson has asked staff to remain "patient" for news about their future positions in the bank and said that any changes would be implemented on a "phased" basis.
Mr Hodgkinson said that the bank was vetting its most senior executives to determine whether they had a role on the new management team.
The bank, which has been effectively nationalised, could face more than 1,000 job cuts under the former HSBC executive's watch. Mr Hodgkinson took up his position at the embattled in late October following the abrupt departure of the bank's former bosses. Mr Hodgkinson said he appreciated that staff wanted to know "exactly how many jobs will be cut, where the cuts will be made, if there will be a redundancy package and what it will look like".
