Throughout corporate America, you'll find your garden variety of different personalities from strategic thinkers, passive aggressive profiles, and of course your ego maniacs. Dealing with difficult people is an art. There's a few ways you can learn to adapt to an environment, culture and difficult circumstances without compromising the success of the project. First, start with the common issues that a difficult person will present to you. He/she will likely try to take credit for the work you completed, or blame you for missing their deadlines. An easy way to handle this is to explain that even though they blamed you, you have no ill will towards them, and actually offered to help with their project so they could get caught up. Another approach is to summarize the issue, then explain that you communicated with the other person and spent time with them to solve the problem.
