Section 2, should the situation be handled any differently if the expectant mother performs a role that could not feasibly be replaced? I do not know how this sort of thing is dealt with IRL, but it jumped out at me as a question.
I assume it would be similar to if she broke her leg or needed back surgery or something. They'd probably hire a temp replacement or find someone already there that can do that on a temp basis. Actually, at least with pregnancy, they'd know about it and have time to prepare. Other things can happen unexpectedly.
I'm not an expert on education, but I feel like the stipulation that it has to be relevant to their profession would prevent that since I think Ed.D are more for people that want to be a principle or superintendant. I'd be open to further clarifying or putting a cap on the length of time though.
