Just because someone has been in the industry a long time does not mean they deserve respect. Respect must be eared (and given). Treating coworkers like garbage will only get you so far, and word travels fast.
I've known art/creative directors who think they are the top shit and expect to be revered. Even worshiped. I've seen people looking for their first jobs melting down into fanboys/fangirls when they meet the industry folks they revere. I’ve known junior artist, who happen to have good talent, expect to be respected and worshiped. Some of these folks (junior and senior) can't even do the simplest art tasks. Especially for what they are demanding from others.
It's wise, from the onset, to treat each other with grace and dignity. Don't get me wrong, Its alright to admire someone, especially if that person is your senior. So long as there is a mutual exchange of respect. Mutual respect goes a very long way.
