The WA Government is facing some heat after it revealed 13 Disability Services Commission (DSC) staff were stood down or sacked in just four months.

Three of those staff had their employment terminated, while the rest have reportedly been asked to remain away from work pending investigations.

DSC policies say staff must stand down while complaints or allegations are investigated.

The Opposition’s disability services spokesperson Stephen Dawson said he was worried by the news.

“These people are some of the most vulnerable people in society,” he said.

“We're supposed to be giving them a high-quality care of service and we're supposed to be protecting them and that doesn't seem that's the case.

“One complaint is a concern but 13 in the first four months does point to some problems existing in the system.

“They are huge figures and the Minister needs to satisfy herself that we are not putting vulnerable people at risk.”

Disability Services Minister Helen Morton says DSC has a zero-tolerance approach, and it is working.

“It is because we have such a strict policy to any concern or any suggested allegation that immediately when there is any form of an allegation people are stood aside while that is investigated,” she said.

“I am absolutely confident the policies and procedures in place are more than adequate.

“We have got 1800 staff working in DSC-provided services and when you look at three people, given all of the circumstances we're dealing with, I don't think that is [a significant number].”
