The "work" involves going to concerts, sporting events, festivals, etc. Best part-time job I have ever had.
Cons
Your hours are dependent on the events. If its not football season, you will probably not have a steady flow of hours. You will also have to stand around a bit.
If you're looking for flexible part-time work, Axis is a great company to work for. You get your pick of all kinds of different concerts, festivals and sporting events. You can sign for as many events that you want to work or only a few.
