I've had the experience of a project manager awarding a subcontractor with work on a project and then immediately quitting to work with for the contractor company.
The PM convinced the sub to lowball the bid, which causes a different set of problems I will not go into. As well, the relationship between the company and the sub has begun to sour.
It would appear that there was no non-compete clause in the PM's contract, and my company seems to have let it slide in order to move forward and just get the job done. From my own perspective, the move to jump ship was fueled by their own dissatisfaction rather than the motive everyone in the thread seems to be assuming first.
Is there a breach of ethics or law for such a scenario just out of curiosity?
I'm not looking for legal advice, more of how to interpret the scenario realistically, the behavior of the PM, and more importantly, any advice on tuning my own behavior as someone stuck in between my own company and the sub that I now communicate with to finish the job, that may not be obvious.
