It depends on the job. If it doesn't involve food or anything near food, then there is usually no etiquette to be done. However, if men with long hair work at a restaurant (or any other place that deals with food), the proper etiquette is to either wear a hat (if it is sort of long, but not too long) or wear a hair net (usually if it is really long). This is usually required for sanitation reasons, but is a common practice of etiquette.

Since the question does not ask on wheter it is on men or women we'll have to address both. Some men find long hair on a woman very attractive, others think short hair is cute, and yet others are indifferent as to the length. As to long or short hair on men, it is based on their own personal preference.
because it is not long
Mohawks, braids, and long hair.
If there is a guy with long hair and he insults you on a new hair cut that you like tell him; At least from behind men don't think I'm a girl that wears men clothes that definitely work. And if it doesn't just say it my hair cut and I like so you'll just have to deal with it.
This is way too broad a question. Please be more specific.
I think not
I know approximately 20000 tracks with men with long hair playing guitars. Please be more specific.
With the times changing and styles changing men change the hair style too. Some of the common hair styles worn by men is the crew cut, bald, or long hair.
