All I can say is, those bashing teachers and rebbe’s have absolutely no idea what the job entails. It’s not a part-time job by any stretch of the imagination.
I was a yeshiva teacher for over a decade. I don’t envy the rebbes. It’s a tremendous amount of work with little money, no job security and no respect.
Most people working for companies get to start their day at 9 and end it at 5, come hell or high water they’re gone.
Teachers need to prepare for their class every night. They have to mark tests, speak to parents, therapists and school administration after school hours. This happens on a daily bases.
