Very simple – if you want to keep the Shtetl mihnagim, then stay home and don’t involve yourself with the “outside world” (and its higher paying jobs).
If you want to work in the real world, then you need to “deal” with some circumstances you might not feel comfortable with or used to.
I am not telling you to shake men’s hands or to eat treif Chas v Shalom, but being referred to by your first name is something that HAS to happen. This is not a Seminary Shabbaton where you are referred to as Miss/Mrs in front of your students.
At my job in BH a nice sized firm, everyone knows that that we Yidden eat Kosher, leave early for Yuntif/Shabbot and do not shake the hands of the opposite gender.
Please enlighten me as to what else we need to be makpid on?
