ADVENTCARE has denied Health Workers Union claims that residents and staff are being placed at risk at its 50-bed Golden Square aged care facility.
About 30 HWU members protested in front of the centre on High Street on Saturday morning, claiming AdventCare had left unqualified staff to provide medication to residents.
HWU organiser Brett Hay said the union had made a number of attempts to highlight concerns with AdventCare.
"We have had 25 letters sent to management from staff telling them that there are serious issues," he said.
"We have contacted the aged care board saying that they need to get their procedures in order.
"We want them to come back to the table and tell us what they have done about it. At this stage, they have done nothing."
Several family members of centre residents also took part in the rally, which lasted about one hour.
In a statement released on Sunday as a half-page advertisement in the Bendigo Advertiser, AdventCare denied the claims made by the union.
AdventCare said it had yet to see "details" of the allegations.
"AdventCare has asked the HWU for details of its allegations and invited HWU to report any concerns to WorkSafe," the statement said.
"As well as causing harm to the organisation, these claims have caused distress to residents, their families and staff.
"We want to reassure our clients, their families and the Bendigo community that AdventCare is committed to providing high standards of care to its residents, to respect for staff and all other stakeholders in the organisation."
