Several hundred people gathered at The Diamond in the town on Saturday to support a rally held by the Northern Ireland branch of the Communication Workers Union (CWU).

The ‘Save Our Site’ rally assembled before being addressed by speakers including the Irish Congress of Trade Unions assistant general secretary Gerry Murphy and others.

CWU NI organiser Erin Massey implored BT, which operates the site, to engage with members and prevent the loss of jobs and damage to the local economy.

She told Sunday Life: “This is a very stressful period for members and we would encourage the company to listen and to talk to us. There was a voluntary leaving scheme but we don’t feel that is appropriate.

“People are going into this blind with the feeling this will be the only offer on the cards but what should be on offer is a proper formal redundancy format and negotiations across 90 days.

“It’s disgusting to treat members this way in a bid to try and save face over the loss of jobs in Enniskillen, the same monies should be available to all members regardless of their circumstances.

“Apparently they are coming to meet local reps next week so we will await further feedback from that because we are not happy at the moment.”

The NI CWU launched the ‘Save Our Site’ campaign last month to try and prevent the loss of jobs at the site.

In February the economy minister at Stormont, Conor Murphy, warned BT it will suffer “reputational damage” if it decides to cut the 300 jobs.

Mr Murphy also said closing the centre would be “completely contrary” to his aims for regional economic balance in a letter to the firm.

BT said a final decision had not been made but its Enniskillen building would require significant improvements to make it fit for purpose.

Earlier in February, BT said it was reviewing its contact centre in Enniskillen and had offered staff the opportunity to take a voluntary paid leavers package, but that no final decision had been made.
