There is both an abnormal amount of promotions that you have somehow personally witnessed -- doesn't sound like you were even involved with, we'll also ignore implicit psychological biases here -- while you happened to overhear THE core group of people involved in some conspiracy to enable your overall incredibly inordinary talking point.

There's a word for this: contrived.

It is extremely unlikely that such a company would exist in the current landscape, one willing to needlessly promote women, especially when considering their prior or current pregnancy status. I'm having myself a pretty big giggle.
