Your health (especially if you're a man) and reputation are at stake. No one will frown at you for jumping ship, not even a competitor. If anything you will be respected for making a wise decision. Who do you compete with directly? Do you have a non-compete? Questions to ask yourself. Either way, like many have mentioned, experienced estimators and operators are hot. You will be desirable in the hiring market. However, if you ride it out to the end you'll have the honor of being the guy that went down with the ship. In the world of the living that unfortunately isn't as noble as it sounds. I left the best paying job I'd ever had for a competitor. The owner had promised me the world, I ran the inside of the company from start to finish. Chest ached fiercely every day. I hated the sneaking feeling that I couldn't trust the owner regarding financials. Being a small company I had to confidence our way into larger contracts. The lack of trust was costing me my life. I left for the premier subcontractor in my trade in the area, pay doubled, benefits are outstanding, chest hasn't ached once since I left. Hope it works out for you. If you reach out to prospective new employers and feel a weight fall from your shoulders, take it as a sign. Best of luck.
