I am in my seventh year teaching, my third at the same school. For the previous two years, I have done a large activity after school, requiring hundreds of hours of work outside of contract time. I got paid when work involved being with students, but not for hours of casting, schedule making, coordinating, etc. This year, I do not want to do it. I already told this to my principal at the beginning of the year and she said ok. Now she is saying I have to do it because there is no one else. I also have two smaller commitments outside of contract hours. I am willing to keep those but not this one. However, they are so insignificant compared to this duty (and one is now over for the year) that my boss likely does not care. The union says I obviously don't have to do it, but I don't think I should bring that up with my principal. I'm wondering what I should tell her. I have had depression and anxiety my whole life and now need to stop medication so my husband and I can start a family. I have also developed hypothyroidism in the last year and am just starting treatment. I have been exhausted for about a year but my insurance refused to treat me and now that I am married and have new insurance I can be treated. I have also lost two family members within the last year. I feel unhappy and stressed and am worried about spiraling out of control when I stop taking antidepressants. I am also worried about getting pregnant because I have fibroids and am in my thirties so I don't have a ton of time to wait and see. A teacher at my school advised me to just tell her I have depression, since saying I was busy, stressed and trying to start a family didn't work. What do you think?
