Guest: Don't write off your future because of this one incident, even if it results in your being fired. From what you write, it sounds to me as though he may have done you a favor. The job does not seems to be ideal for you anyway if you are frightend of your boss.Any prospective employer worth his/her salt, is going to take into account your thirty year record, not just this one incident.
I would advise you to be upfront with those who interview you. Tell them that your last employer was a tyrant and that you do not expect that you will receive a good recommendation from him. If you have multiple years of employment with that company the intervewer surely will take that into account when considering your present employer's comments. After all, if you served the company for a considerable period of time and your employer was so dissatisfied with your work, why did he keep you around so long?
View this as an opportunity to open a new world for yourself. If you are in the U.S., work opportunities are abundant in most parts of the country. Go at it, and be positive.
I wish you the very best.
