Hey BL,

Not having any specifics here is some general advice.

Make sure you have created an email trail to record any attempts to report/resolve the matter and keep track of responses, advice or direction from your employer. The system is geared to protect those in authority, those who can make the decisions and address the issue may avoid getting involved by using the buffer of HR and compartmentalisation that allows them to claim plausible deniability.

Get some assistance, I'm guessing you're not a union member. I'm not familiar with US labour law but if you are feeling threatened or stressed due to being victimized then your employer should at least attempt to address your concerns as a matter of health and safety.

I would advise that you fwd your complaint to every senior manager HR and above including directors or owners. Given that you have no support from your collegues you should request that have a support person attend any meetings or interviews to discuss report/allegations.

Good Luck,
peace.
