Pros
The company offers good benefits, and they are genuinely concerned with keeping their employees happy. There are many opportunities to provide feedback about your work experience, and there is constant dialogue between the workforce and management. Employees are an integral part of the policy making process.
Cons
Everyone starts on the overnight shift, and because turnover on the day shift is low, you can expect to continue doing nights for at least a couple years. By the same token, promotions are challenging to get because you are competing with people who have 10 years or more experience. Hours are frequently long and the work is physically demanding. Sometimes you will go for weeks putting in 10-12 hour days, on your feet that whole time, with infrequent breaks. Other times you may struggle to get a full 40 hours. Because the business needs change regularly, they go through frequent rounds of lay-offs, often followed a few weeks later by a big hiring push as the overtime skyrockets. In the 5 years I worked there, we went through 4 rounds of layoffs.
