The company is looking to temporarily close the mine that is running at a significant loss.
Tara Mines workers have agreed to proposals to support them while they're laid off work.
All unions involved recommended the proposals be accepted.
Workers at Tara Mines this morning voted to accept proposals relating to the lay-off of 650 staff.
The proposals include a guarantee that workers will return on the same terms and conditions of employment when the mine reopens again.
There will also be an increase in the number of people who will be retained for care and maintenance of the mine during its period of closure.
The deal was recommended to members by all the unions involved. And they say staff will receive a "modest" retainer allowance for the workers who are being laid off.
Tara Mines, which has been opened since 1977, will temporarily close tomorrow.
Adrian Kane, a divisional organiser at SIPTU, says the Government needs to do more to protect the workers at Tara Mines:
Staff at Tara Mines in Co.Meath say they are hopeful they’ll be back at work within a few months.
Mike Allen, who has worked at Tara Mines for 38 years, says it’s a sad day for employees:
