[OH] Harassment

What other resources are available besides HR?

My mother works at an elderly facility where a new guy just started, well he is threatening to “stab her with a dull knife and feed her to pigs”, he tried to trip her and stab her with pencils or throws things out of her hands.

I told her this is unacceptable and she needs to speak up. Well the boss overheard this and just ignored it, watched him be physical and ignores it or other times he has harassed her by making sexual jokes her boss laughs.

She is looking for a new place and is afraid to report him to other places for fear he may actually do something.

He is married and has 6 kids…I worry about them…

What more can I encourage her to do and what can I do to help?

Thank you for any help! OH |OH|

Edit: her manager is also considered HR (it is a messy business)
