Don’t hire them - Problem solved
That's definitely the answer. Even if I'm the HR Mgr or the Dept. Mgr hiring for these openings and all I have are Americans with bad employment history or a Muslim, I'll take the bad employment history any day of the week and work with them on being a better employee. In the end you save all the attorney fees associated with the prayer Bullsh*t fiasco...
I guarantee they are infiltrating the work place only to create themselves as a victim.
