Clr Margaret Gormley called on Junior Minister John Perry to stand by his commitment that the Tubbercurry Government offices would remain open, as promised before the last general election.
She said that the first premise opened in 2006, with another two years later.
"They employed 100 people, which was a major boost for Tubbercurry and its hinterland.
"These people bought houses in the area and their children are going to local schools.
"In the last 12-18 months, a number of employees have been transferred to Ballina and Castlebar.
"It appears that Taoiseach Enda Kenny is looking after his own people and patch."
There are now 32 people employed in the Tubbercurry offices, pictured below.
"The loss of 70 jobs to an area the size of Tubbercurry, could be compared to 2000 losses in Dublin or Cork.
"It is important that the remaining jobs are kept in order for small businesses to survive."
She added: "If John O' Mahony can do it for Claremorris, then the Minister for Small Business and Deputy Tony McLoughlin can do it for Tubbercurry."
