Pros: we got free lunches all the time, mondays was donuts and coffee day and we also got frequent bonuses.
Cons: i really can't think of any cons i working in a optical warehouse.
I worked in the A/R section of the lab i would clean the lenses and ring them,place them into the ultrasonic and finally place them in the oven to dry. The hardest part of my job was making sure that the lenses were not scratched and making sure that we don't scratch them ourselves while cleaning or ringing them.
