Go to whoever your boss is and explain very professionally that you have concerns with legalities and the way things are being run. Explain that you wish to stay on board but that things are going to need to change. Use specific examples of the issues you are having. If they tell you that its not a problem and they won't change anything, then explain that you will have to move on because you fear that your certificate is at risk. If they acknowledge the problems and fix them, then stay until the one year mark. Aviation is a small community, so do everything professionally and that reputation will follow you around. That includes staying at minimum a year after someone gives you a type, unless they are breaking the rules. Then you need specifics to explain your situation later when it comes up.
