Mona was a human services worker in a prominent transitional living center that serves adults, adolescents, and children. She was also the program director of the center's alternative school, which serves adolescents with behavioral health challenges who have difficulty functioning in traditional schools. The program's staffers provide teens with counseling services as an adjunct to their classroom activities. Mona was one of the counselors.

Mona, who is married and the mother of two young children, is currently on a leave of absence from her position due to "personal issues." Next week, she is scheduled to appear in court to respond to allegations that she became sexually involved with a 17-year-old transitional living client enrolled in the alternative school.

According to the complaint that the teen's parents filed, Mona developed an intimate relationship with her client. The relationship began with an exchange of suggestive and provocative text messages and evolved into caressing and a series of sexual encounters that took place in Mona's home. Through her attorney, Mona admitted to the inappropriate relationship. Mona also faces another challenge: the parents of her former client have named Mona and her agency in a lawsuit that alleges that she engaged in malpractice and that both she and her agency are responsible for the harm her unethical and illegal conduct caused. The detailed lawsuit claims that Mona's former client has endured serious emotional injury that has interfered with his ability to finish high school and pursue gainful employment.
