Representatives from Siptu and management of Fás have begun talks at the Labour Relations Commission in a bid to avoid industrial action due to be held tomorrow.
Last month, Siptu members at Fás voted overwhelmingly to take industrial action in opposition to the Government's decentralisation programme for the State agency.
According to the union, only six of the 400 Fás head office staff have expressed their wish to move to Birr, Co Offaly, but that since it was linked to promotion, that number had risen to 28.
The work stoppage will last for two and a half hours from 8.30am to 11am on April 5th and will see pickets being placed outside the head office on Baggot Street and at Fás offices on the South Circular Road and on Adelaide Road.
Fás has said it is implementing Government policy.
