I am a preschool teacher at a private Christian school, and I'm currently 21 weeks pregnant. I teach a three-year-old class on Tuesdays and Thursdays, and a four/five-year-old class on Mondays, Wednesdays, and Fridays. I informed my director about my pregnancy when I was around ten weeks along, as my belly was already quite noticeable. The staff has been very supportive and excited for me. I recently learned from a coworker that the school is taking my three-year-old class away from me because they are unable to find coverage for both classes during my maternity leave. They plan to hire a new teacher for my threes class and only find a substitute for my other class. I was not approached about this decision directly; I had to ask my director if it was true, and she confirmed it, citing the difficulty of finding coverage as the reason. This situation is particularly upsetting because I have been with the school for five years, and parents have specifically requested me as their child's teacher for the upcoming year. I feel that my income is being negatively impacted, and I'm concerned about the legality of this decision. Is there anything I can do to address this situation?
