Pros: Rewarded if you do well, generally easy labor, friendly clientele, free membership
Cons: No full time, no benefits, no promotions, no references
In a nutshell, this job is great for college students and bad for everyone else. There are no full time positions available and there are no positions between you and your director. Where you start is where you finish unless someone retires.
You do get recognized for a job well done, and the jobs available are pretty easy for the most part. Free membership and paid sick days are the only perks.
