Marian High School, an all-girls Catholic school in Bloomfield Hills, Michigan, fired Webb after she requested pregnancy leave. The school viewed her pregnancy as "nontraditional" and against the school's morality clause, Detroit Free Press reported.

Since going public with her story, Webb, 33, and her wife Kristen have seen an outpouring of support. Over 100 people gathered for a protest and rally for Webb on Sunday, and about 3,700 have joined a Facebook group, "I Stand With Barb Webb."

Webb taught chemistry and coached sports at the school for nine years. Upon learning of her pregnancy, the school left her with two choices: Resign and be silent, or be fired. She said she chose to be fired and refused to be silent about her story.

"Speak out against hate wherever you see it," Webb wrote in a Facebook post. "Whether it's writing a letter or calling Marian or setting a safe place in your own school or business. Don't be afraid to be the change that so many of us need you to be. It is only when the masses can stand up to injustice that we all may have a chance to fulfill our life dreams and ambitions."
