There actually is a follow-up to this story that confirms that this person has not overcome her strong tendency to bully, her narcissism and her fixation on the victim: https://www.askamanager.org/2017/12/update-i-didnt-get-a-job...

She rather pities herself at length than putting some effort into admitting and reflecting on the wrongdoings. Similarly to the ‚probably was awful to her’ in the first letter, her fallout (obviously retraumatising the victim at her anniversary) which got her thrown out of a restaurant and blacklisted in the industry gets a short sentence worth of description.

I hope for the victim that she could avoid that person.
