Crew members are important pieces to the operations of a certain establishment. Most generally, crew members work in the food industry, but they are known to work in other industries as well. Because there are so many opportunities attached to this position, education requirements can also vary.
The best part of being a crew member is that you're part of a team. You work together as a team and fail as a team. That's the same people who are going to have your back at work, so you might want to spend some time getting to know them as best as you can.
