Police will not be rushing off to non-urgent calls today, as they take industrial action against the state government.
The work-to-rule campaign means officers will not work unauthorised overtime or make themselves available after hours, and will return to their station for a meal break and to complete each task including paper work.
The action is part of a push by the WA Police Union, which is demanding stab-proof ballistic vests, more officers and a 1.5 per cent pay rise for the force.
Union president George Tilbury says there will be no imminent risk to community safety during the campaign.
"The Premier and all other politicians, and the Commissioner of police are well aware that our members wanted stab proof ballistics vests, as that was part of our pre-election submission that we released in November last year, " he said.
Premier Mark McGowan says the action is unnecessary, and the wages policy the government has brought in, is fair and reasonable.
"The state's financial position is catastrophic. We can't afford large pay increases," he said.
