said by bobnoxe:They can work, they simply work in an place where everyone shares the common language, and they aren't customer facing.
Which extremely limits not only their potential employment, but also their potential income. Say I owned a restaurant in a primarily Muslim area, where everyone spoke Arabic (which is moot given the extremely specific dialects Arabic has based on region), I still wouldn't hire that person if they couldn't speak English because not only would no Canadian customers be able to be served by this employee, but even 2nd and 3rd generation canadian customers who are of Muslim recent may not necessarily speak Arabic any more.
