Fairfax Media will cut 45 jobs through the merger of business reporting across three newspapers and the closure of glossy magazine inserts.

The company announced in an email to staff that the jobs would be cut after shutting its Sydney and Melbourne magazine inserts, and integrating reporting teams from The Australian Financial Review and BusinessDay, part of the Sydney Morning Herald and The Age.

The company is seeking voluntary redundancies from 25 business media staff and 20 employees from the News Media and Life Media magazine section.

Fairfax last year announced it would cut 1,900 jobs as part of a restructure in response to declining circulation and advertising revenue. The latest cuts are part of the 1,900 job losses.

The head of the company’s Australian Publishing Media division, Allen Williams, wrote to staff on Tuesday and notified them of meetings being held with affected staff in Sydney and Melbourne.

“The current revenue environment remains challenging,” he said in the email.

“While we are satisfied with the actions we are taking to address these challenges, we must also find cost reductions across our business.”
