Not that I complained at work, but I'm not one to let someone come over and push me aside. Not in the least.
In one case some managers in our company decided there was some problem that needed fixing. They proceeded to hire a bunch of H1Bs from a body shop and started them working. The managers neglected to tell any of us programmers what was happening.
I spent a bunch of time answering a bunch of questions from a guy who was obviously desperate to do a good job, but with no real direction.
They eventually canned all the folks with nothing getting done. And it only cost our lame-o dot.com company about $1,000,000! One of the cheaper mistakes they made.
