Stress
Looking at tickets and pointing at rows of inevitably uncomfortable fold-up seating isn't exactly a recipe for stress unless you're the sort of person who loses their mind when presented with a balcony ticket while ticket-checking the orchestra pit. And if you're that sort of person, well, this is probably the only job you shouldn't be doing.
It can, however, be stressful to deal with an ever-changing schedule, and not knowing when you'll get another back-to-back two days off. And how about wondering whether or not they'll let you even hit forty paid hours of work that week? Funny how the people who make the least amount of money typically also face the most uncertainty. It seems sort of unfair, doesn't it?
