lol this is great, I would do this, I can't see why this is not accepted as normal. How is this any different than a developer paying a building company to build a house and the building company contracting a plumber or a driver. It was giving the sub contractors the unauthorised access where he went wrong, posting his 2 keyfob etc. He should have run a proxy at his house and made the guy connect through that, never would have got caught. But it is still bad faith and I would not be happy if i was an employer.
I have joked about out sourcing my own job as well. But didn't think it was actually plausible, until now.
