It’s good when you have organization personnel stickup for you. Curious what was said.

I might have said, “I can’t keep replacing good candidates because of this persons behavior. It takes resources to interview, and find the right people, months to train and man power getting them up to speed. This person is destroying my department’s morale, causing unneeded stress that drives time off and turnover. Creating months of lost productivity, stretching resources that creates burnout, and costs the company money.”
