Commonwealth Bank rehired 45 customer-service staff after its AI voicebot rollout raised call volumes instead of cutting them

Commonwealth Bank of Australia (CBA)·An AI-powered customer-service 'voice-bot'

CBA cut 45 customer-service roles in July 2025 after introducing an AI voice-bot it said had reduced call volumes enough that staff were no longer needed for simple queries; weeks later the bank reversed the decision and apologized to the affected staff.

Blast radius

45 employees were let go and then had the decision reversed; the Finance Sector Union said call volumes at the bank had actually risen, increasing overtime for remaining staff and requiring management to be drafted in to answer phones.

Root cause

The bank based a staffing cut on the AI system's projected effect on call volume before confirming that effect held up in practice

How it was caught

Rising call volumes and overtime after the cuts, surfaced publicly by the Finance Sector Union

What changed

CBA apologized to the 45 workers and did not proceed with the redundancies; it also separately reported 'mixed results in utilization and efficacy' from its use of GitHub Copilot for engineering
