Pros
You get to do substantive work sometimes. Overtime is nice during the busy seasons. Breakfast provided Mondays and pizza on Fridays. Looks decent on a resume.
Cons
Training is inadequate. Most of the learning is done on the job. Nobody knows your name, and nobody really cares. Everyone keeps to themselves, smiles are hard to come by because the employees realize how much they hate their jobs. During my time, I didn't hear a single positive thing about the company. Temps are completely expendable. You can work 60 hour weeks and deliver exceptional work but they have no problem cutting you lose when it becomes convenient for them. They will replace you by the next morning due to their careless hiring strategy. Most temps are hired without even an interview. It makes it easier for them to let you go. Little to no advancement for permanent employees.
