Rob and Alex can't write jack for female characters these days. Heck, if you think Uhura is incompetent, just watch how many times she leaves her station just to see Spock off or see him when he arrives. There are no less than three communication related tasks that a Communication's officer would be assigned to do but she doesn't get the assignment.
Her role is entirely useless.
Hahaha. So true. It actually got annoying how she was following Spock around so much.
But with regards to the point of this thread, she probably did inform her superior in Communications on Earth, but that doesn't mean it made it up the chain of command to Pike, especially since this all happened in a day.
