Prateek and Nancy are peers working in the same project. He was attracted to her and had asked her out several times but she always said no. The last time he asked her out, she told him that she isn't interested and wants him to stop asking her out.
Although he stopped asking her out, he then started staring at her continuously. He stared at her during the client meetings, in the elevator, at the cafeteria and all the time possible. When she catched him staring, he didn't bother to look away.
This goes on for a couple of days post which Nancy raises a formal complaint with GRB team.
