He's made his reputation and career doing things his way,...for better or worse. He wants you to do it his way to protect both those things. Completely understandible. If he's normal, after you gain his condfidence in your ability through your work effort, these comments and remarks and such should stop.
Now, if he's just one of those guys whose always looking over your shoulder and micro managing every nail you hit, I suggest you learn to deal with it while you gain as much knowldege and experience as you can and then move on when opportunity knocks.

Couple of ifs:
If you are technically proficient and if you have worked around in the trade
for a number of employers and this guy is an exception to your bosses treatments of you, then it's likely his issue.
If other bosses have dealt with you in a similar way, then mabye your technical and or people skills need improvement.

Every client tax return I sign, I personally review most of the data from source info to the finished product. It's my a$$ on the line. It's how I do business. Mistakes are costly.

Hang Tough!
