Workers stage rally over Pluto plans

Up to 2,000 workers from Woodside Petroleum's $12 billion Pluto project have taken to the streets of Karratha to demonstrate their anger over the company's plans to implement a "motelling" arrangement.

ABC Radio today reported that the workers staged a march in the town over the issue, which has prompted two strikes over the past two months, the latest on Friday.

"Motelling" refers to a process where workers will have to pack up their belongings at the end of a shift and be allocated a new room at the start of their next rotation.

On Friday, an estimated 1,000 workers walked off the job after being threatened with eviction from the accommodation at Gap Ridge by Woodside and contractor Foster Wheeler Worley.

Up to 3,500 employees work at the Pluto project on a usual day.

A Foster Wheeler Worley document issued on Friday outlined that workers needed to sign an agreement by the end of the day, or remove their belongings from their room by no later than noon today.

Woodside's argument for the motelling arrangement is that it would provide more people with an opportunity to work at the project, with 25 per cent of the rooms normally vacant under the current scheme.

Further comment from Woodside was being sought at time of publishing. The Australian Manufacturing Workers Union was not available for comment.
