In rural Nebraska, my mother was let go for being pregnant with me from a bakery. As a teenage mother-to-be in her Sr. year of HS she was strongly encouraged to drop out by school administrators because it wasn't appropriate for other students to see a pregnant student. This was in the early 70's. I can't vouch for Warren's situation nor know any details but my mother's relayed personal experience loosely conforms to Warren's. On the flipside my mother-in-law, a retired teacher, worked for the same school district in Tacoma WA for 30+ years and had 4 children between '69 and '75 without issue. Clearly there were more enlightened areas of the country.
