The Union is calling on the government to ensure workers continue to get their entitlements.
650 Tara Mines workers still don't know when the Meath mine will reopen.
The news comes as SIPTU calls for job-seeker's safeguards for staff.
The union has written to Social Protection Minister Heather Humphreys to ensure there's no reduction in social welfare payments.
Adrian Kane, SIPTU Divisional Organiser, says the government needs to step in and make sure workers get their entitlements, in line with what they've received for the last 13 weeks:
