I'm coming up for 17 weeks gone and haven't told work yet. When I was 6 wks pg, our CEO indicated that there would be a redundancy in our department and without saying so directly, made it pretty clear that it would likely be me. I have been waiting to get to the 20 week stage so that I would qualify for SMP but am so evidently pg now that it seems silly to wait and if they did try to let me know, I would make a claim for SMP.
