West Australian Newspapers is cutting 110 jobs through voluntary, and possibly through forced redundancies, by the end of the month.

This was announced by the company's chief executive Chris Wharton through an email sent to the staff today.

According to Mr. Wharton, the job cuts are required by the company's current thrust to restructure. He said it is essential for the publications to streamline to cope with industry changes and economic challenges.

Bound to be affected by the job reduction are the production and sales departments, and also the regional operations. About 40 people from the editorial section are expected to vacate their positions, according to editor-in-chief Bob Cronin.

Geoffrey Thomas, union representative at West, believes that a good number of the editorial staff will choose to leave voluntarily.

Based on released guidelines, the staff are given only two weeks to freely leave their posts. After which, they may be forced to leave through redundancies.

Management is expected to hold a briefing today for employees.

The West Australian Newspapers is the company that publishes the West Australian and the Community Newspaper group. It is also responsible for the publication of 21 other titles across various regions of the state.

This is the third job reduction that the West has undergone in recent years. Four years ago, the company also enforced around 90 voluntary redundancies. In September 2012, it also cut around 15 editorial jobs.

The job cuts come at a time of alarming decline in West's circulation numbers. Today, the newspapers' daily circulation is pegged at 174,000, while the weekend issues number to 300,000. This is a considerable dip from five years ago when the company used to enjoy a daily circulation of 195,000 and 342,000 during the weekend.
