made complaints about her co-star before the February 20 clash that ended The Kyle and Jackie O Show, a new report has alleged.
The radio star raised 'multiple' grievances over a 14-month period before she was terminated by ARN, news.com.au claimed on Tuesday.
Henderson 'made repeated verbal and written complaints to the radio network' about Sandilands' behaviour towards her, both on and off air, a source told the publication.
She will argue that ARN failed to provide her a safe workplace and unfairly terminated her contract.
The report also alleges that Henderson did not ask for Sandilands to be fired, nor did she want her own contract terminated, and instead had asked for a 'solution'.
A source told news.com.au that Sandilands was not made aware of these complaints prior to his termination.

'There was nothing like that, they acted like it was over that (February 20) disagreement,' the source alleged.
Daily Mail has reached out to ARN for comment.
Both Henderson and Sandilands are now suing ARN, and the lawsuits themselves are nothing short of explosive.
Sandilands is pursuing a claim believed to be worth up to $85 million, while Henderson has launched her own legal action alleging adverse action and breach of contract.
Henderson is seeking compensation of at least $82.25 million, as well as a pecuniary penalty plus interest and costs.
She is alleging the termination of her contract was a breach of the Fair Work Act.
Henderson has filed in the Federal Court against the Commonwealth Broadcasting Corporation, a subsidiary of KIIS 1065's parent company ARN.
She is claiming that the termination of her contract 'constituted adverse action.'

ARN says it denies the claims and will fight the case in court.
If both claims land anywhere near their reported figures, ARN could be staring down liabilities exceeding $160 million – well above its current market capitalisation.
