Shirley Was Recently Recruited as the HR Specialist for a Bank

Shirley was recently recruited as the HR specialist for a bank. Two weeks later, the accounts receivable clerk, Bonnie, approached her to inform her that she is being sexually harassed during her lunch break. Other employees taking their breaks in the same location and during the same time have started making sexually explicit remarks directed toward her. If Shirley is following the law, she will:

A) hold off this complaint until she is approached by the others as well.
B) explain to Bonnie that her complaint will be considered sexual harassment only if the others ask her for sexual favors.
C) explain to Bonnie that in order for the complaint to be considered sexual harassment, at least one of the persons she is accusing must be her supervisor, or someone who outranks her at work.
D) take proactive steps to address this situation.
