The Dublin Alliance of General Construction Operatives is to hold a mass meeting of workers next week which could cause major disruption at building sites in the capital.
The organisation is angry at its exclusion from the negotiations on health and safety, pensions and pay initiated between employers and unions after the recent scaffolders' strike.
"For too long we have been treated as second-class citizens in this industry," said Mr Andrew McGuinness, chairman of DAGCO, which claims to represent up to 10,000 labourers and general operatives.
"It is disappointing to think that in this day and age we may have to revert to industrial action to achieve inclusion in a review of our working conditions."
The meeting is in Liberty Hall on Wednesday, August 18th.
