HR folks cannot be trusted to curb it, let alone stop it, because more often than not, they're buddy pals with the bully. I worked for a high-end retailer from 2010-2020 and dealt with bullying, abusive management almost the entire time; I always jumped in to help a colleague in need, I was always on time, I was never late, I learned the operations of the three stores I worked in during this time and, somehow, I was viewed as a threat. In February of 2020 I was laid off; I got two month's severance and cashed out my 401K. This company I jokingly refer to as 'The Hen House', and I will never go back to work for them.
