I have three questions.
1) Can a religious Orthodox Jewish employer, refuse to employ a Non Observant Jew on Shabbos or other Jewish holidays, if the Non Observant Jew volunteers to work on this, since the Non Observant Jew has always worked on Shabbos and Jewish Holidays all his life in other jobs for other non Jewish employers.
2) Can a religious Orthodox Jewish employer refuse to hire or employ a Jew that converted to another religion on Shabbos or any other day, because of the religious Jewish person's beliefs are against someone who left the religion and sees them as an Appostolate?
3)Does a non religious Jewish person have to inform his religious Jewish employer if he is indeed Jewish as well, because he feels that if he does inform the employer, the employer will not allow him to work on Saturday, when the non religious person needs the extra income from Saturday work.
