Can I be fired for stepping down from a managers position?

The answer to this question depends on the exact situation, subtleties of the job position, and personal experience. Of course, each case deserves individual approach, but if speaking in general, there is no exact information that stepping down is hands-down connected with firing. Let’s say, if the job as a manager simply doesn’t suit you because of some personal characteristics, you can explain this to your boss. He or she will evaluate the situation. But let’s be honest, if you want to step down because you are not responsible enough, you can try pushing a bit harder and step out of your comfort zone. Maybe, you simply underestimate your potential. So, before doing this significant step, be 100% sure that you have a reasonable explanation. Then your boss won’t think about your unprofessional approach and won’t consider firing you as an option
