My boss thinks he can fire me because I'm rude and have life lessons to learn however I'm not rude I even call him sir all the time and apologize when needed too

Thank you for your question. Your boss would not be able to terminate you for cause for the reasons you have described. That said, your boss could terminate you without cause and you would be owed severance. I would strongly encourage you to visit the severance pay calculator our firm has developed to see what you would be owed if terminated (www.SeverancePayCalculator.com). If terminated, I would also encourage you to call us right away.
