Thanks arranfan!
It seems that Liberty Counsel is a not-great Evangelical Christian organisation, but they've got it right here.
It seems to be a very minor story only pushed by them, so hasn't made major news, but also genuine.
I found their statements on their site, here

And there's also a pdf (will auto download on mobile,) here

Excerpt:
Both of the P.E. teachers, Robert O. and Stephanie C., objected to administrators’ orders to allow the girl into the bathroom, with no forewarning of the boys, or their parents, so that the boys could take steps to protect their privacy. Administrators told them that informing the boys so they could take steps to protect their privacy would be “discriminatory,” and subject them to discipline.
Robert also objected to administrators’ order that he continue to walk into and supervise the locker room, despite a girl potentially being nude or undressed in that area.
The administrators told him that the girl in question had “every right to use the locker room,” including the right to disrobe in the open locker area, and shower in its open showers, where Robert is required to periodically walk in and supervise. Robert will not knowingly place himself in a position to observe a minor female in the nude or otherwise in a state of undress. Now, Robert has been told by administrators that he will be transferred to another school as discipline for “not doing your job in the locker room.”
Yesterday (Thursday, September 27, 2018), the girl was admitted to the boys locker
room for the first time, and walked in, catching boys (literally) with their pants down, causing them embarrassment and concern by the fact that they had been observed changing by an obvious girl. Boys immediately came out of the locker room, and approached Stephanie and Robert, seeking assistance. The P.E. teachers were powerless to respond, because administrators had placed a gag order on them, and told them that they could not answer the boys on these questions. Today, boys were asking Robert why he is not supervising them. Again, he was not able to respond.
No law requires this course of events. Objective biological sex – male and female –is (and should remain) the determining factor for access to gender-appropriate public school facilities and programs, not subjective mental “identity” claims or beliefs that one is the opposite sex, or a feeling that one is not one’s actual biological sex. The District is violating male students’ and teachers’ rights at Chasco Middle School.
