Losing Job position due to Pregnancy?

Kristy

So, I'm gonna start from the beginning. I have been employed with my company for 12.5 years. 9 of those years I spent working my way up to salaried management, which I have spent the last 3 Years doing. On January 16th I had a TIA (mini stroke) this caused me to miss 8 weeks of work and because my vision was still messed up My employer wouldn't let me return due to needing to possibly drive cars in and out of the garage, or so they lead me to believe. Earlier this week I was informed that they had my position posted while I was out on fmla because by the tia I was released to full duty my 12 weeks of job protected leave were up. An hourly associate came to me and told me they were filling my spot when I go on maternity leave. I left this go with a grain of salt because the rumor mill is a vicious cycle. But the thought of losing the job that I worked so hard to get being stripped from me because I'm having a baby got the best of me. So, I went to my manager and he informed me that the rumor was true. And they previously had me replaced but I returned before the job offer was signed. My questions to you are, have any of you been through this and, how did hourly employees know about this devastating news before me. Oh yeah and my manager knew this was the case for the last 6 months and his reasoning for not telling me was because I'm high risk. This year has been not great. TIA, lost my grandmother, watched my father die for 5 months, my home was hit by a flood, and now I'm Losing my job, because of the one miracle my beautiful baby girl, my little glimmer of hope this year. Any advice?
