As a general matter, an employer may terminate you for giving a coworker advice, such as about which managers or shifts are better, how much you think she should be paid, whether a work assignment was fair, etc.However, an employer may not terminate someone for reporting sexual harassment. While what you are doing is not directly reporting the harassment, you are involved in the reporting process and are helping an employee to make a report: it is reasonably likely that if you were to be terminated for your role in this, that would be considered illegal retaliation and you might therefore have a legal claim, one you could bring to the federal EEOC or your state's equal/civil rights agency.
