The nurses union has warned it could take industrial action as soon as next week after the State Government yesterday made a pay offer the union says falls far short of its demands.
The Government offered nine percent over three years but the union is pushing for a 20 per cent pay increase.
Australian Nurses Federation state secretary Mark Olson said that under the State offer, an extra 1.25 per cent a year was also available but only if nurses agree to sacrifice other benefits which were yet to be specified.
"We'll start hospital stop work meetings on Monday, at those meetings the nurses will be asked hospital by hospital, whether they want to put in place bans on non nursing duties and I expect it will be an overwhelming yes," Mr Olson said.
Non-nursing duties would include anything not directly related to patient care, including cleaning, filling, restocking and answering phones.
"It will have a big effect on the way hospitals are run," Mr Olson said.
Mr Olson described the offer of three per cent over three years as "grossly inadequate" and said Health Minister Kim Hames was out of touch.
"It's guaranteed to keep nurses in the lower end of nursing wages across the country," he said.
"It is the type of offer that will guarantee they won't be able to open Fiona Stanley in a few years time because they simply won't have the nurses, the nurses will go elsewhere."
Mr Hames has been contacted for comment.
