Leading Melbourne trainer Peter Moody says he has acted in the best interests of his staff by giving them the chance to look for other jobs.

Responding to a News Corp report, Moody confirmed he had given his staff notice of their employment in the event he was banned over cobalt use.

Moody is due to front the Racing Appeals and Disciplinary Board on December 14 over a positive test returned by his horse Lidari when it finished second in the 2014 Turnbull Stakes.

He said the decision to put his staff on notice was not an admission of guilt.

"In relation to this morning's article in the Herald Sun, yes I have my staff on notice in regards to my upcoming cobalt hearing and have given them all possibilities to look at moving forward regarding their employment," Moody said in a statement.

"I believe I would be derelict toward them as an employer if not up front about all possible outcomes.

"This in no way is an admission of guilt regarding upcoming hearing and is certainly not on the advice of my legal team."

On Monday, the RAD Board began the hearing of cobalt charges against fellow Victorian trainers Mark Kavanagh and Danny O'Brien.

The case entered its fourth day on Thursday.
