The Chuncheon District Court handed down the sentence last weekend, also ordering the woman, who is in her 50s and works in a restaurant kitchen, to complete eight hours of sexual violence prevention education, Yonhap reported.
The incident occurred on Oct. 3 last year at the restaurant where both individuals were employed. Although the events leading up to the act remain unclear, the woman pulled down the pants and underwear of a male coworker in his 20s in front of others.
Prosecutors charged her with committing an indecent act by compulsion, citing the sexual humiliation caused.
According to The Korea Herald, the judge dismissed the defendant's claim that the act was intended as a joke.
The court took into account her admission of guilt, the fact that it was a first offense, her apology to the victim and his parents, and other mitigating factors when determining the sentence.
