How can outsourcing be viewed as a human rights issue? Well, first of all, the Universal Declaration gives us all a right to work:
Everyone has the right to work, to free choice of employment, to just and favourable conditions of work and to protection against unemployment.
As well as a right to an adequate wage:
Everyone who works has the right to just and favourable remuneration ensuring for himself and his family an existence worthy of human dignity, and supplemented, if necessary, by other means of social protection.
Outsourcing can mean that people lose their jobs, and the threat of outsourcing can mean that people are forced to accept lower wages. Or course, none of this implies that there is or should be a right not to have your job outsourced to some foreign country. But outsourcing can still be viewed as a human rights issue. Even more so if we look at the receiving end. For people in India, for example, outsourced jobs can mean the end of poverty. And poverty is a human rights issue.
