Pros
A large percentage of the employees are kind, interesting, engaging, smart people of good character. Your role will not be limited to the "traditional" tasks associated with your job title - you will have the opportunity (necessity) to reach beyond those and contribute in other areas also.
Cons
You will not be rewarded or even acknowleged for exceptional performance. Management has been in total chaos for at least 5 years and remains so today. They do not have a plan - nor do they communicate decisions effectively to employees. There is no accountability at the Executive level - instead, their responsibilities are pushed down to the middle managers without commensurate authority to make decisions or produce outcomes. Getting a policy decision that is comprehensible is impossible. Senior Management will not remove barriers to progress, nor attend to the fundamentals necessary to enable middle and lower level employees to achieve good outcomes. Management will violate your trust, as was done with the December 2009 and June 2010 bonuses, which were not paid - and there was no communication of this intent by management until they were already overdue. The executive team simply does not respect employees, nor any contract that is signed. Getting management to deliver what has been promised in a contract with a customer is nearly impossible, so you will always be stuck between an exasperated and hostile customer and an incompetent, irresponsible Executive.
