Lead Petty Officer of a 12-person communications center. It was frustrating because whenever someone disagreed with my decisions, they could always go over my head and get a lieutenant involved. Even though the lieutenant usually sided with me, it was the time wasted on dealing wit 'attitudes' that caused me the most trouble.
Lead engineer on several design projects. Even when I gave clearly-defined standards and expectations, there was always at least one person who believed that he or she had a better idea. Sometimes they did; mostly they didn't.

The keys are to inspire others, lead by example, communicate clear expectations, be open to new ideas, and watch your back - the smiling face that agrees with your every word will likely hide the mind of a person intent on taking your job.
