They can already do this easily with the stock market.
Usually though people's pay/power directly correlates with how badly they can screw the company if they go (legally) rogue.
But anyone can get a job at XYZ, buy puts, and go and set the factory on fire the next day. Betting markets don't change the fact that you'll be arrested, except that you'll be arrested for a few thousand dollars rather than whatever you can squeeze out of options.
The difference is if someone sets fire to a factory that fire will be investigated and odds are that person will be caught (not always, but few people know how to set a fire that large and cover their tracks). By contracts someone who works in the factory is much more likely to be able to figure out how to "have an accident" doing something they normally do, everyone knows it is then but they just get a "do better next time" talking to, and the factory throws up some more guards.
