My favorite boss, the one my wife reminds me of each time I come home a little worked up from my current employer...
I started a new design project. I was new to the industry, but was well versed in all the skills needed to perform well because I was using those skills regularly in my prior job. Also, the company actually did a really good job of maintaining lessons learned from prior projects so I had a really strong basis to start this project.
I finished the project within a few weeks. Handed it over to my boss for review. (Which, by the way, everything goes across his desk. It was the biggest bottleneck in the company.) He said that was too quick and I couldn't possibly have finished it yet. Go back and review it some more.
I put it on my desk then surfed the internet and read trade journals. After a suitable amount of time had passed, I turned it back in for his review. Upon his review, he recommended a few changes because everything has to be done his way. I debated the changes with him, and decided my best option was to concede and accurately document the cause for the design changes.
I had the prototype built and tested; it failed. My boss looked at the design and said these things are wrong, fix them by doing this. The things that were wrong were the changes he "forced" upon me. His fix was just a reversion back to my original design.
By the time the project was over, we were about a month late on delivery to the customer. We should have delivered a month early.
