121 jobs are to be lost with factory closures in Dublin and Mayo.

40 jobs are to be lost at the Oasis Watercoolers manufacturing plant in Ballina, Co Mayo.

Workers were told that the company plans to transfer its manufacturing operation to Poland.

It said the decision had been forced on it by increased operating costs.

The company, whose parent firm is based in Ohio in the US, is to retain 15 jobs in Ballina. It came to Ballina in 1992 and at its peak employed a workforce of over 100.

The town's Chamber of Commerce has said the decision is a further blow to the town, which has lost 1,300 jobs in the past nine years.

Elsewhere, 81 jobs are to go at the PCTEL factory in Finglas in Dublin. The parent company, based in Chicago, said the PCTEL’s financial losses are now at an unacceptable level.

Plans are under way to transfer the technology operation to eastern Europe.
