Nursing staff at Mildura's Bupa aged care facilities and facilities across the State will see industrial action taken as part of a campaign for better pay and staffing levels.
The action follows Australian Nursing and Midwifery Federation members rejecting two 2.5% wage increases in a two year agreement.
The union claiming the offer still keeps its nurses and carers' wages in the bottom 10% of aged care facilities.
The first stage of action involves staff wearing red, T-shirts by the ANMF and handing out information about conditions to residents and visitors.
The union claims a Bupa registered nurse earns over $4700 less a year than industry standard rates, with enrolled nurses and carers also paid thousands less than at competing aged care facilities.
Negotiations will continue.
