AITA for reporting coworkers who don’t engage with our organization’s social media posts?

I work in social media for a public organization. Part of my job is monitoring the performance and engagement of our social media accounts.

For a week or two, I had been reminding employees that management expected them to stay active and engage with the organization’s posts. Despite multiple reminders, some employees rarely or never interacted with the content.

Recently, our manager asked me to prepare a list of employees who had the lowest engagement with our social media posts. I didn’t come up with this idea myself; I was specifically instructed to provide the information, so I did.

Afterward, one of the employees on the list called me and was extremely upset. She said things like, “Who do you think you are to mention my name in meetings?”, “It’s a good thing you’re not in a higher position,” “Now I know what kind of person you are,” and even, “If you have a problem with me, say it to my face so I can put you in your place.”

The thing is, I don’t have any personal issue with her. I was simply carrying out a task assigned to me by my manager. I wasn’t making decisions about discipline or consequences; I was only providing the requested data. I was close to her that I’m kind of afraid that she would spill my secrets to everyone. AITA?
