Delaney will also take a pay cut, meaning his salary will drop from €400,000 to €360,000, but has warned that there may also be compulsory redundacies as the FAI tries to implement cost-cutting measures.
The letter was sent to employees, who must agree to the cost-cutting measures by Friday, 24 August in order to "protect jobs and to assist in the future sustainability of the organisation".
Delaney warned staff that anyone agreeing to the measures will face a pay cut, as shown in extracts of the letter printed in the Irish Independent: "You were advised that this would involve changes to be made to your contract of employment including a salary reduction and a suspension of contributions to the pension scheme.
"As you are aware, this request is necessary in the current climate and your acceptance is vital in order to achieve the necessary savings."The FAI is due to meet trade union SIPTU at the Labour Relations Commission on Monday as staff members threaten to strike over the proposed cost-cutting measures. The pay cuts would be the third reduction in the last 18 months imposed on FAI staff.
Meanwhile, the FAI has announced an under-17 international friendly double-header at Milebush Park in Castlebar, Co Mayo next week against Azerbaijan. New U17 head coach Tom Mohan takes charge for the first time, with many English-based players included in his 19-man squad.
