do you think the discrimination towards working and pregnant mothers at work are real in singapore?

Yes. My manager was really unhappy when I got married and the treatment got even worst when he found out I was pregnant. For something really petty, I got a warning letter for taking too much MC (once a month for check ups). Had a counselling session with HR, Manager and General Manager but they were talking rudely to me till they noticed my phone and became paranoid, questioning if I was recording the whole conversation which I wasn't. Immediately, they spoke to me super nicely, claiming to "understand" my delicate situation. But in the end, still received a Counselling/Reprimand letter and a Warning letter. Kind of sad as I had a really good reputation there with no issues till I got married and fell out with my manager.
