Pros: Can't think of any
Cons: Kids, Staff, Parents, Company policies
I worked at our local club house for a few months, and I didn't like a single day of it. It is now under a new manager whom I worked with when she was only staff, and I hear she has changed to place around for the good. I'm only speaking for my time as staff there, and so things may be very different now.
Most of the kids there were little terrors, and there was little to no support from the parents or management. There was several times some of the kids should have been removed from the club permanently, but the management at the time was more concerned about club membership than the safety of the staff or membership.
For example: We had a set of siblings that liked to threaten the staff by saying things like "When I get home I'm going to tell my mom you hit me, and you're going to get in trouble." They would do this because you told them clean up their mess, stick with the program schedule, or something they didn't want to do. They would go as far and hitting each other to make it look convincing.
It wasn't a great environment as a male staff member, and I really didn't like it. There was a lot of sadness with some of the kids. They would arrive as soon as the door opened in the morning, and they would be the last to leave Monday - Saturday. A lot of the parents just used it as a daycare for their kids.
The parents were sometimes very very hard to work with, and would threaten to sue you or something. The made the job even more enjoyable some times.
