refused to present with her former radio co-star 'ever' again after their relationship broke down in the middle of a live show, according to damning legal letters.
The letters form part of a tranche of documents released by the Federal Court on Friday amid Sandilands' lawsuit against KISS-owner ARN Media over the termination of his $100million contract.
ARN axed the deal after a segment on the Kyle and Jackie O Show on February 20 when Sandilands slammed Henderson for her 'fixation' on astrology.
Henderson said 'that's not fair' and left the studio in tears, before her own $100million contract was terminated. She has not launched legal proceedings.
Less than two weeks later, on March 3, Sandilands received a letter from ARN accusing him of making 'abusive, humiliating, and belittling comments' to Henderson, which included attacks on her character, work ethic, and job performance.
'You stated that everybody at the radio station was talking about these failings, thereby impressing on her the idea that her conduct and performance was so bad, that they were generally the talk of the station,' the letter read.
ARN claimed Sandilands' comments were not made in jest, and showed 'manifested hostility' towards Henderson that was 'calculated to offend and distress her'.
The broadcaster claimed Sandilands had damaged the business because Henderson refused to 'ever present with you again'.

Days after the blow up, Henderson released a statement saying she 'did not quit or resign'.
Sandilands was given 14 days to remedy the situation or his contract would be terminated, but ARN did not propose any solutions in the initial letter, or subsequent letters.
He was ordered not to comment on the situation, not to disparage anyone at ARN, or victimise anyone who made complaints about his conduct, or risk having his contract terminated.
A response from Sandilands' lawyer Kevin Lynch on March 10 claimed the broadcaster was aware of his client's 'tone, style, voice and robust character', to the point where it was willing to pay him $100million.
Mr Lynch also pointed out the fact that the broadcaster had 30 seconds to censor and remove any disparaging comments before they went to air, but had chosen not to remove Sandilands' remarks about Henderson.
He said ARN created a 'Catch-22' when Sandilands was not given a way of resolving the situation.
The court also released an affidavit sworn by Mr Lynch, who described Sandilands and Henderson's respective on-air roles and their long working relationship.
Mr Lynch said Sandilands was the 'dominant and abrasive personality who is deliberately outrageous and often offensive', while Henderson was a 'warmer and more emotionally attuned character.'

'The characters which Mr Sandilands and Ms Henderson play are designed to be an exaggeration of their respective personalities.'
