alt Hacker NewsIf you don’t have a duty to report, you don’t have a duty to report. You can’t predict what government prosecutors will do. If they start investigating and it turns out for whatever reason they can’t pin it on the boss, they could have pinned if on OP.
Think about it logically. If you’re the prosecutor, the guy whose time is fraudulent is presumptively the criminal. It could very well be that he was actually the one who was engaged in the fraud, but went to the authorities to protect himself by making it look like his boss did it.
Yours is unfortunately the attitude which breeds corruption, and also the attitude of the majority of people. "Not my problem", "not my duty", "covering my own ass", "not getting into trouble" and so on. The reptilian minded people like OPs boss love having you guys around, because they can't do their unethical schemes just by themselves, and you won't make a fuss.
As for the prosecutor; he is first and foremost interested in where the money went. If fraudulent hours didn't give OP an extra paycheck boost, then that money went somewhere else.
