Nikki, I don't think he was threatening to let me go if I got pregnant at all. My boss is, how shall we say, COMPLETELY politically incorrect. You should hear some of the things that have come out of his mouth. When I was pregnant with DS, I went into his office to complain about someone on campus who was giving me a REALLY hard time. He actually asked me if this was ME talking or my pregnancy hormones. He's always making sexist jokes.
Oh, my hubby and I met at work. We started ttc a couple of months before our wedding (we were living together too) and I got pregnant about 2 months beforehand. I was so excited that I let slip at 6 weeks that I was pregnant (I ended up miscarrying at 8 weeks which is why I wanted to wait until my first trimester was over this time). Instead of saying 'congratulations' he made it very clear that he didn't approve because we weren't married (he's pretty religious). The man is harmless enough, but completely oblivious.
When he came into my office last year and asked if I was planning on getting pregnant anytime soon, I think he was worried that a) I might leave after baby #2 (as several other women who work at the college have done in the past few years) or b) taking another 4 month maternity leave when we were a staff member short would be hard on the office.
My main worry with telling him right now is that he will question my hours again. I've been trying to slip under the radar because last year he had told me that DH and I couldn't keep our work hours indefinitely. I'm so scared that he'll make me go back to regular work hours. I can't and won't do that and my family can't afford it right now, you know? Sigh.
The good news is that I told my direct supervisor who is a step up from me and step down from my boss. He was ok with it. I didn't lie at all- I told him that I was afraid to tell our boss and what he said last year. He would like to go with me when I tell my boss. He even asked if I was planning on keeping the same schedule and I told him that I wanted to so much and since our hours worked well and no one has ever complained, I would like to continue them indefinitely. He seemed to think that that wouldn't be a problem. So now I'm a little calmer about telling my boss but I'll have to wait until Friday because I'm in training all day until then.
