I emailed a new teacher that recently came into the tech program I'm in. It is a program full of women, and I know the students and especially directors can be very unkind and cut throat.
I know it takes a lot of getting used to, and I don't know for sure if she's been feeling discouraged lately about it, but I reached out to thank her for all the hard work she does for us students. Sometimes you just need to hear that you're appreciated. I hope my email did that.
Women should support women! Not cut them down.
