As my name states, I live in CT. Far enough away from NY to enjoy open space, but within a 90 minute drive to NYC.
That said, the close commute to NY is used by Yeshivos and Shuls to lower the pay rates for rebbeim and Rabbis. Applicants are told that it’s an easy trip in to Monsey, Queens or Brooklyn to see family, shop, eat, etc. Therefore you are not sacrificing as much as communities 3 hours or more away from the city and we can pay you less.
Also, it is quite common for rebbeim to teach a full day in out of town day schools/Yeshivos. They may teach elementary in the morning and High School in the afternoon or vice versa.
One of the biggest problems ion employment is that many of these Yeshivos (particularly Chabad) have become dynastic, employing mostly family members. Non family members tend to be hired for a year or so and when they seek a raise they are not retained and another beginner, who comes at beginner salary is hired.
Tuition discount is not a selling point for employment, faculty kids attend free.
