Evan Luzi puts together some aspects to think about when working with the hard-to-work-with.

Like any job, going to work in the film industry isn’t always fun. Stepping on set can become a chore when you’re stressed from a shoot, feeling pressure from your department, andworking extremely long hours.
So the last thing you need in a situation like that is someone treating you poorly: berating you, yelling at you, and generally being a damn asshole.
But it happens.
I wish I could tell you that everyone in the film industry is nice as cherry pie, but statistically that’s impossible and, from personal experience, I know it’s not true. At some point, probably early in your career, you’re going to encounter an asshole. How you deal with them will have a tremendous effect on the path your career takes — for better or worse.
It’s like I mentioned on his blog, having self-confidence and confidence in your work, regardless of the perception of another party, can help you triumph in these circumstances.
It really is tough if you are below the line. The assholes know there are lines and lines of people who want to work in the industry and they’ll take advantage of it every which way. Then there’s the fact that the whole industry is a dream factory so big egos come into play. Sometimes producers aren’t trying to be assholes, but they just aren’t considerate and the pressures of the business gets to them.
