In response to a problem about finding a job and being Shomer
Shabbos(keeping the Sabbath), there is one basic principle we must keep in
mind; that is, we must have full emuna(faith) in Hashem that he will support
us and sustain us, especially when we must "sacrifice" something for His
sake. In truth, we really are not "sacrificing" but taking. In regards to
not being able to keep a job because one is Shomer Shabbos, we "sacrifice"
our job, but in truth, we take the merit of the mitzvah of keeping Shabbos,
acting for the sake of Heaven, and many other merits. Many stories are told
that Jews who immigrated to the United States from Europe in the first half
of the century often could not keep jobs for more than a week (if that
much!) due to the fact that they had to keep Shabbos and the Yamim Tovim.
Nowadays, agreements can be made with bosses and owners to get around from
working on Shabbos or Yom Tov.
Good luck and Yasher Koach!
