While I’m appalled at what happened to your daughters, there is a lot of motzei shem ra on our yeshivos.
A few years back, while in college, I worked as a teacher assistant in a Brooklyn Girls school and as a teacher in a Brooklyn Boys Yeshiva. I got paid ON TIME and FULLY for what we had made up (verbally) at the beginning of the year. It was a wonderful experience for me and while I would have continued teaching, sadly it doesn’t pay as well as my proffession.
PLease dont’ generalize and throw all Bais Yaakovs and Yeshivos together.
