Last year when I was in the Osaka based General Union, we received an email from an Interac ALT who was rather upset because she had been fired for being pregnant. Martina (name changed) was set to have her contract renewed with her school where she was loved by her students and teachers. Her contract had already been promised to her verbally and her schools and students were looking forward to her return. Then, people in the Yokohama office found out something that they viewed as a major inconvenience to their business, Martina was pregnant and would be giving birth during the middle of the school year.
They told her that in light of her condition, it would be too much trouble for them to find a replacement in the middle of the school term, and had decided to go with someone else who was less…. pregnant.
