Pros
If you want to spend your last 10 or 15 years before your retirement without doing much work for a reasonable pay, this is your ideal place to work.
Cons
New ideas to save the cost or improve the network / system / process are devalued. Management bully the employees who challenge their ideas ( which is always to satisfy their 1-Ups. ( I was bullied by my 1-UP for doing a good effort for the company and my 2-UP told me once that he could allocate me to a shi--y work if I don't comply. Fortunately, I left once I finished my projects ) Mishandling of public funds. Eg. GMs & Project directors hire consultants / contractors from their ex-colleague's friend's / associate's firms while internal resources could be used. There is no motivation to reduce the cost. Every new senior staff will wipe out an ongoing project work and team and will re-start the programs with their puppets. Widely advertised current Network Transformation Program is such an example. ( Previous projects , tenders , supplier selection were disrupted and hired new consultants to run the same outcome)
