1- Rabbi Oelbaum form Machon Bais Yaakov always calls teh girls by MIss last name. Zehirus in Tzniyus.
Maybe a girl in the workplace can not use her regular hebrew/affectionate name but use a formal version or even a secular version to be used just in the secular environment…… prevents her form feeling close. Rebbeca instead of Rivka, Judith instead of Yehudis, “Raitchel” instead of Rochel etc………
I know of too many single girls who fell prey to the new fund freedom and excitement of relationship in the workplace………… big time problems……. serious ones……. Enough alluded to. Harchakos are in order.
