There is a pressure on the people to outsource much of their work at market price, skimming the profit. People are clever, they will find a way.
It also puts an immense value on getting the job (possibly by deception or by getting rid of the incumbent in some way), and then staying at that job at all cost. The risk-aversion will be through the roof. There will be absolutely no back-talking. The managers will never be challenged, no matter what they do, by their underlings. Morale and the working conditions will deteriorate as a consequence, with negative effect on the bottom line.
All the above used to be the norm in various forms in the Soviet bloc when I was a kid. Those of you who spent some time in a socialist country will recognize the problem.
I hope that this experiment stands the test of time, and we can all learn from it how to make employing people more humane. But I won't be holding my breath.
