Minister of State for Employment Damien English has said the Government has not been told by Twitter how many people the company will make redundant in its Irish operation.
Speaking on RTÉ's News at One, Mr English said that the IDA will continue to engage with Twitter in an attempt to minimise job losses but said that there are vacancies within other businesses in the tech sector.
"We don't have the exact number of people who will be affected by this and naturally the concern of all of us is those individuals and families who will lose their jobs," he said.
Mr English said while the Government does not yet have the numbers, "we do expect them to engage with our department in the days ahead which might give us a clearer picture of those numbers".
He said that there continue to be vacancies within the broader sector.
"There's an opportunity but it's also a difficult time, nobody wants to be made redundant."
Asked if Twitter had broken Irish employment law by starting the process without engaging with the Government, Mr English said this was "not necessarily" the case.
"Those processes only kick in 30 days before dismissals happen or before the redundancies happen. There is time for the company to follow their obligations and I would expect them to do so," he said.

Asked if Twitter had started engaging with the Government on this, he said: "That hasn't formally started yet, I checked again late this morning... I would expect that to happen formally in the days ahead. We've got very strong protections here for employees under Irish employment law."
He said there are no indications yet as to exactly how many job losses there will be in Stripe or Meta, either.
"We hope it will be minimised," he said, adding that we are in "a very strong position" in Ireland in terms of employment in the tech sector.
Some companies "over-estimated" their growth and took on people because of this and some are now engaged in an effective recruitment freeze, he said, but he didn't have "a list of companies" affected.
"The Irish economy is in a very strong position but we have to work hard at that as well."
Labour Party spokesman Jed Nash said it is a "really worrying time" for those employed in the tech sector and that there have been "issues in the undergrowth" in the last number of months, and not just in Dublin.
Speaking on the same programme, he said: "All the indications were that there was going to be a correction this year and some of these firms were in fact overvalued."
Mr Nash said: "There was probably an inevitability that some firms overshot the runway."
He said he was "a little concerned" to hear from the minister that there's a lack of information about the numbers of job losses involved and that the Labour Party has been saying for some time that there's a need to diversify our economy.
