Pros
The work is challenging and varied. It will keep you interested since there are always new problems to tackle. Great colleagues who are supportive and willing to help/train you on anything you need. Laid-back work environment. Great place to get started and learn the ins and outs of publishing and get hands-on experience before taking it elsewhere.
Cons
The sheer volume of work is daunting with most people doing 2-3 people's amount of work. Poor compensation ($32,000-$35,000) for the amount and level of work being done. They do promote and give performance increases, but raises are small and insignificant after tax. People are doing senior-level work without being paid accordingly. Incredibly high turnover because of the low pay and high stress. Hard to keep moral high when there is constant turnover and no improvements. Quality of the books being published is poor. There is not a lot of room for upward mobility after one or two promotions. When people resign, there is a an air of indifference from upper management because they know you can be replaced by someone who is right out of college who is willing to take a lower salary to start their career.
