Avantages
Good work life balance, pretty good benefits. Some positive direction and changes for the CEO. Fairly stable company. Non-confrontational environment. There are many long time employees, so the environment must work for some folks.
Inconvénients
Depends on your particular department, but beware many areas reflect a very traditional company, hierarchical, resistant to change, slow to change. (Many management, collaboration and other cultural norms seem to be stuck in the 1960 - 1980 period.) C level management is making some positive changes but it's yet to be seen if it will trickle down throughout the organization. There are many long time employees (particularly in middle management) that find change very threatening. You need to be very comfortable with incremental change to be satisfied here. Even suggesting any substantial changes can cause fierce (and at times punishing resistance). But if you can get comfortable with the slow pace, mediocre outcomes and keeping your opinions to yourself, they pay is decent and they don't work you too hard.
