The 1,500 staff at Ulster Bank in the Republic are considering strike action over waht they see as management's refusal to address staff grievances.
Mr Larry Broderick, general secretary of the IBOA saidthe grievances include shortage of relief staff, a new expenses policy and inadequacy of branch security.
Mr Broderick explained that the IBOA has held a series of meetings with its members in Ulster Bank over the last couple of weeks, through which he says it has become clear that there has been a deterioration in the attitude of management who are seeking to impose change without consultation or agreement with the Union.
Mr Broderick added "Given the significant increase in Ulster Bank's profitability in recent years, it is only fair and reasonable that staff working for Ulster Bank are treated with the respect and dignity they deserve."
