Ms Roberts went to the Fair Work Commission alleging she had been bullied by her employer, mainly in her interactions with Lisa Bird, the sales administrator and the wife of the agency's principal.

Ms Roberts said when she complained to the agency principal James Bird that she was not getting a fair representation of her properties displayed in the front window of the agency, Mrs Bird called a meeting and accused her of being a "naughty little school girl running to the teacher".
