Thanks for the advice and comments. After I spoke with my director this morning, she gave me 3 weeks paid, 4 weeks unpaid and 4 weeks of working on "flexible, part time" schedule.
I am trying to get as much paid maternity leave as possible but I work for a non-profit in Baltimore, MD and my boss isn't trying to give me any paid leave. She isn't even trying to completely follow FMLA because we have less than 50 employees. What should I say to her when trying to negotiate my maternity leave?
