Pros
Flexible scheduling makes this a good place to work if your in school, though mistakes in the schedule by management might not be corrected. general friendly atmosphere, good people in general, though it has become less and less friendly since the last management change. Employment is stable, few people are fired, though transfers from department to department are often forced.
Cons
Nonstop drama, incompetent upper management, to the point where you can barely do your job, getting full time means jumping through a series of insurmountable hoops, equipment either barely works or doesn't work at all, little or no training for any lower position. You will be expected to do 2 or 3 peoples work for no additional benefit. Little room for growth, since most managers are hired from outside the company.
