Nearly 200 Optus call centres workers in Adelaide’s northern suburbs will lose their jobs in the coming weeks, their union says.

Employees at the Mawson Lakes centre were told about the job losses on Tuesday after Optus said it would slash 480 positions Australia-wide, according to the CWU.

“The northern suburbs have been hit again and it’s not good news,” Communication Workers Union SA and NT branch president Graham Lorrain told AAP on Wednesday.

Steven Butterworth from the Australian Communications Workers Alliance says workers were shocked at the news.

“[Workers] are quite depressed,” Mr Butterworth told the ABC.

“I was talking to a gentlemen yesterday who has been working for Optus for the last eight years as a technical support person and has a young family, and he’s devastated. That’s the only way I can describe it.”

According to Mr Butterworth, some workers could be finishing up at the call centre as early as four weeks’ time.

“There will be a small group kept on for several months during the transition period,” Mr Butterworth said.

Optus has been contacted for comment.
