I don't know what I'm going to do...

As the title states... I've worked as a seasonal temporary full-time employee for a corporate insurance company for a little over a year now. My princess is due next month, so naturally I figured I would start getting my FMLA set up. Now since I am not a full time salaried employee I do not get the paid maternity leave benefits, health insurance, PTO, or disability insurance. But, after a year and/or working 1250 hours I should qualify for FMLA... Well I found out today that apparently I haven't worked enough hours (they are claiming I only work part-time) when I work full-time hours, to qualify for FMLA and are telling me they are willing to give me 4 weeks unpaid leave and that's it. I don't know what to do, but I feel like I'm getting pulled under the bus here. Literally in tears because this is not fair. Does anyone else have experience with this or know what to do. I'm considering calling the Department of Labor tomorrow.
