A lot of us are going to work on set as an assistant at some point in our careers, and with that job comes a certain set of responsibilities and expectations for behavior. Here are eight things you definitely shouldn’t do on set. 

The conducting teacher at my school always says: “If you’re early, you’re on time. If you’re on time, you’re late. If you’re late, you’re fired.” I used to think it was a bit of an overly dramatic sentiment to encourage students to learn to be professional, but the older I get, the more I agree with him. If you walk in the door right when something is set to begin, you’ll be behind every time. Coming to you from Jay P. Morgan of The Slanted Lens, this video details how a lack of timeliness and seven other behaviors are one-way tickets to never being called again. Really, it comes down to knowing your role on the set and respecting the time, authority, and creative direction of those running it. I liken being an assistant to being a sports official: if at anytime in doing your job you make what’s going on about you, you’re doing it incorrectly.
