Seven West Media’s national management announced a major shake-up of the network yesterday, including the axing of flagship current affairs show Sunday Night.

Seven Adelaide’s PR manager, Libby Rayner, who has been with the network for 20 years, finishes up tonight, with publicity activities to be centralised in Sydney. Interstate reports have suggested that up to 100 jobs could go across Australia.

Industry website AdNews reports that Perth’s publicity department was spared the axe “due to its close working relationship with The West Australian” newspaper, also owned by Seven West media.

InDaily asked Seven West Media whether there would be further job losses in Adelaide.

“We’re not commenting on specific roles or numbers in relation to yesterday’s restructure,” a spokesman said.

Seven CEO James Warburton yesterday foreshadowed sweeping changes to the company’s structure, aimed at simplifying its management and reducing duplication.

Warburton was appointed in August, replacing long-standing CEO Tim Worner. Just days later, the company announced a $444 million loss for the 2018/19 financial year.

Yesterday, Warburton said he was aiming to simplify Seven’s structure “to enable our content-led growth strategy”.

“This new flatter structure will cement our position as Australia’s leading media group with content at the heart of the business, digital growth maximised, duplication of roles removed in all areas and operating efficiencies implemented,” he said.

“We have had to make some tough decisions in order to build the network for the future. I take very seriously any decision that impacts our people and I am grateful for the loyalty and commitment shown by our team over many years. Anyone impacted by changes will have dedicated support and respect throughout the process of transition.”
