Pros
I'm a 20 year old college student who easily got a summer job as a seasonal Merchandiser. Pay was $11 an hour(not bad for a college undergrad) plus .55 per mile driven in personal vehicle.
Cons
No work life balance. Be prepared to work every weekend and holiday. I personally didn't have a set schedule so I only knew if I was working the night before they would send a route to my company BlackBerry. I put 1,000 miles on my own car from working 3 months over the summer. Guy I trained with didn't teach me anything at all, I was just extra help to him. Work day was from 6am until done. Sometimes this meant working a 12 hour day depending if you had to build displays and if deliveries came in. Store managers could be so rude and everything was your fault. Backrooms had no space, were very disorganized, and pallet jacks were old and broken.
