Telstra will let go 92 workers from its wholesale and finance workforce, the telco confirmed today.
It said it would create 38 new positions at the same time.
Telstra said the cuts were a result of proposed changes to its back office business processes, as well as its billing resourcing.
The Community and Public Sector Union said Telstra was planning to offshore its wholesale billing and order provisioning and delivering functions, as well as some transactional wholesale facilities access functions.
Affected workers are spread across Adelaide, Brisbane, Canberra, Melbourne and Sydney, the union said.
The CPSU also said 20 roles would be made redundant in Telstra's software engineering team. At the same time 25 new roles would be created, it said.
"Decisions that impact our employees are not taken lightly," a Telstra spokesperson said.
"As our wholesale business responds to increasing competition and prepares for a post NBN environment, these are the difficult decisions we need to make to evolve and support our new growth areas.
"We are working with those impacted to help them look for appointment opportunities within and outside of Telstra. We do not expect the proposed changes to have any disruption to customers."
