My Workplace Disciplined Me For Making A Cps Complaint

To start, I am a mandatory reporter. I live in NM, USA, and reported my workplace to CPS in good-faith. I work at a child shelter, and had a concern over the safety of a child. I made the complaint either Friday or Saturday and informed my then physically present supervisor prior of my intent to file the complaint.

On Monday I informed my direct supervisor. I emailed her the case worker # and case #.

Well, come today I find myself sitting in a disciplinary meeting, being told I violated workplace policy by not reporting the CPS complaint to the program supervisor (this is written in our internal policies).

The CEO told me she was upset that her or the program supervisor were not one of the first to know about the complaint. She said it looked bad in the community. Basically, feelings were hurt.

If they had just come to me and said hey, next time tell this supervisor, not that supervisor I would say "thanks for the clarification" and we'd all go about our business. However; they made this an official disciplinary meeting, which is big, because 3 disciplinary meetings can lead directly to termination.

Can my workplace legally discipline me for the manner in which I (a mandatory reporter) filed a good-faith CPS complaint? Or is this illegal retaliation?

***Edit: My workplace "X" has an additional internal policy which states "X will not interfere with an individual's right to report child abuse." I could be wrong but it seems to me that disciplining me for the delivery of my CPS compliant is interference

***Edit2: I appreciate the responses, I think it might be important to clarify: The report is against my own place of work, and actions in which the program supervisor was complicit. Specifically, that a child was permitted to have and smoke cigarettes.
