You might get along with your boss, your boss might seem great and be a nice guy. You might even be friends. Hell, he may even mean well and genuinely want what's best for you. But always remember:
1) At the end of the day your boss' job is to take as much from you as possible and give you as little as possible in return. Same as customers. The difference the company makes there is literally the definition of profit.
2) If you're non-union in the US, you have zero power. Your only real recourse to any grievance or unfair treatment is to quit, forgoing your severance and losing your health insurance. Your only weapon is a freshly updated resume.
Additionally 3) Even a geniune nice promise from your boss probably won't consider your risks. Human brains only are good to evaluate the risks to themselves, and if you don't get what the boss promised the risk to him may be relatively low.
