Telstra has called for voluntary redundancies from 120 of its network delivery workers in a bid to pare its technical workforce.

The Communications Workers Union reckons the move is down to Telstra’s “failure” to win “any major part” of the NBN construction work.

The union said it expects some of the 120 positions targeted under the voluntary redundancy program would be outsourced.

In the last two months Telstra has confirmed plans to cut more than 200 jobs across its finance and service operations and 326 customer support jobs.

Many jobs have consequently been outsourced.
