Oh it was very expensive in the last job I worked. You needed to redo everything we got back from the cheap labor there.

I automated most jobs that I was told to send there. Since due to the quality issues only the busy jobs were sent there that are faster to automate and higher quality, too.

After a few months my boss came to me and told me I need to use the outsourced staff more, since they have nothing to do.

Outsourcing != bad hire. Sounds like you just did bad hires, whether that's outsourced or not is diagonal.

I'm a business owner, and we do extensive outsourcing, with a very good outcome. The trick? We outsource from our home region (where I emigrated from), so we know the market better and how to hire well.
