Avantages
Very flexible scheduling. Work does not go home with you. If you are a hard worker and reliable you can be outsourced to other companies (if you are willing) where you can learn new skills and, depending on the job you're outsourced to, have the possibility of extra bonus income. This is a great job for someone who wants supplemental income while still having freedom from the usual demands of most jobs.
Inconvénients
Not much room for growth within the company (as it's not a huge corporation). Hours are hit or miss. Some times in the year you might have as few as 20 hours a week. Other times (summer mostly) there is a lot of overtime (1.5x pay for every overtime hour) working up to 84 hours. This is not a great job for someone who wants steady income throughout the year as hours do change without much notice.
