Much is written in the media about the 'slave wages' and sweat shops of Asia. This concept is outdated and virtually irrelevant when it comes to skilled 'white collar' roles offshore.
When it comes to offshore labour, there are two key ethical concepts that tend to concern both Australian employers and the public generally: the ethics of working conditions, and the ethics of low wages.
Generally speaking, Australian employers show the same behaviour offshore as they would show in Australia. They run offshore teams because it makes businesses sense to do so, not because they have a diabolical urge to oppress the poor. They therefore spend money on wages and work environments that are conducive to getting a high quality result, and more often than not this means paying above market rates for wages, and utilising A-grade office environments.
