Unions representing workers at Aer Rianta are meeting senior officials at the Department of Transport this evening to discuss the future of the company.
The 5 p.m. meeting comes days after unions voted overwhelmingly for industrial action over the proposed break-up of the company.
Three unions - SIPTU, Mandate and the Technical Engineering and Electrical Union (TEEU) - voted for industrial action following a refusal by the company to provide guarantees about conditions of employment in the event of the break-up going ahead.
IMPACT union, representing managers, expects its ballot result later this week.
