Telecoms company Avaya is cutting 64 jobs at its operation in Sandyford in south Dublin.
The group, which is owned by a private equity company, is consolidating its functions with an operation it owns in Galway.
This morning the staff in Sandyford were told they would be paid statutory redundancy.
The company is now entering a consultation period with staff.
The workers were also informed they would lose their positions on the last day in September.
In addition to the 64 job losses, another 34 people will be transferred to the company's Galway operation.
About 40 people will remain in corporate roles in Sandyford.
The company has been grant aided by the IDA. Today a spokesman for the IDA said there was a procedure in place in situations where any company owes any liabilities to the State agency.
