The Archdiocese of San Francisco and teachers at four Catholic archdiocesan schools have reached agreement on a new contract. Catholic San Francisco, the official publication of the archdiocese, summarizes the terms this way:
A new labor agreement between the Archdiocese of San Francisco and the union representing teachers at the four archdiocesan high schools states that Catholic teachings must remain paramount in the classroom and that teachers are accountable for personal conduct that could negatively affect their ability to serve the Catholic mission.
I haven't read the agreement so I cannot comment on it, but further details can be found here.
