I've been in this situation and fortunately I came to my senses. The board hired a sociopathic CEO who was running the company into the ground and driving away all the good engineers. I came up with a concrete and inexpensive plan for turning the company around which I thought had about a 50/50 chance of making the company so successful it would own its market, which was brand new at the time. It was largely simple stuff like not making the same dumb mistakes over and over. I thought about taking the plan to the board, and then I realized: A. The board members talk to the CEO every day, but I've never even met most of them. Who do I think they're going to listen to? B. Everybody on the board is rich. If those guys lose $50 million they shrug their shoulders, sail to Bermuda for a month of R&R, and get right back on the investing horse. C. I owe the board members nothing. NOTHING. I was hired as a staff engineer, not as a turnaround expert for a failing company. D. The most likely outcome of me talking to the board is me getting fired and nothing else changing. In fact that's the only realistic possible outcome. So I quit. And immediately got a better job. The company continued declining and eventually fired the sociopath CEO but by that time a better company had come along that now owns that market. You can't fix stupid. All you can do is leave.
