My staffer asked me why we do not offer a donor service on our web site. I explained that our web site was testing a similar service for another branch of the organization and that we were not ready to move forward.
She responded by sending me a list of other organizations that do offer this service. I told her I was aware of that and that we would pursue it when we were ready.
I found out today that she went around me to our web developer and asked her to make the change to our site.
The staffer ignored my answer, refused to accept "no" for an answer, and breached my trust (and the trust of our web developer, as well as the developer's time).
Suggestions? I am not an overly strict supervisor per se (don't read that much into that!), but I cannot accept this behavior.
