The NSW Civil and Administrative Tribunal (NCAT) heard Yelda felt "her reputation in the male-dominated workplace had been tarnished, and her co-workers would look at her differently" as a result of the posters.
It accepted Yelda "nearly collapsed … felt exposed, humiliated and ashamed" after seeing the image, which she initially thought was doctored when it was sent to her via email by a male colleague.
Another male colleague encouraged her to make a complaint, telling the court his first impression of the image was a woman pointing to the word "lubricate".
She quit soon after lodging her complaint, and the court accepted Yelda "could not face everyone after the poster was displayed" despite being a highly-regarded worker.
It found her inability to return was "fundamentally" because of the posters. She has not been employed since quitting.
Having found her a "credible, reliable and honest" witness, the tribunal ruled Yelda had suffered psychological harm and a loss of $318,280.08.
The court was only able to award $100,000 against each respondent: Sydney Water and Vitality Works, which produced the poster.
Both argued around $10,000 was reasonable.
Sydney Water accepted Yelda had been embarrassed by the posters, but argued she had circulated them widely in national media and had initially downplayed the poster's impact on her.
