I am a new tenure-track assistant professor who is expecting a baby in January (just after spring semester starts). I will be arriving on campus in the next couple of weeks and need to tell my department chair I am pregnant quite soon, as the teaching assignments for spring classes will be made shortly.

I am assuming that I will not get any leave and I will need to teach my spring class, either in person or online. This is because I am in the US, and FMLA protections don't apply until one has been employed for a year and the university doesn't offer anything beyond what is required by FMLA.

My current strategy is to shoot the chair an email mentioning that I am on campus now and that I hope we can meet before the semester starts. During the meeting I plan to be straightforward and tell her I am expecting. I will tell her I am hoping to stop my tenure clock for a year and ask her to strategize with me on how to meet my teaching obligation in the spring, given that I will be due around the second week of classes.

What are the most important considerations when having this type of conversation with my chair?
