Pros
There are a lot of talented journalists working for Gannett who still believe in news. Since Gannett is a giant company, you may have access to better resources than family-owned outlets in similar markets would. It's somewhat common for middle managers to move around between Gannett markets, so if you can't advance at your current location you may be able to move up somewhere else.
Cons
There's a huge disconnect between the high-level ideals upper management espouses and the way middle management actually operates. Everything is very political. Hourly employees can expect to work unpaid overtime trying to handle the absurd workload. Exempt employees can count on working constantly. The company isn't very good at cross training, so it's difficult to find people to cover for you if you have any kind of slightly specialized skill. A colleague of mine once had to work remotely from a hospital waiting room while his mother had surgery for some kind of cancer. Gannett's customer service is so bad that employees in just about any role will have to deal with it from time to time. Lots of angry calls/emails and no way to know if you've actually fixed a customer's problem. Pay is low, though consistent with industry norms. Health insurance is kind of pricy and not a good deal for anyone who actually uses insurance (the $1500 deductible also applies to prescriptions and normal office visits, wtf).
