Pros
If your ingrained in the group you can get away with doing very very little, and with no career skill advancement on your part. If your lucky, you can get a very good paycheck for doing nothing, and not even showing up to work. Heck get an IT management position and not even know what SDLC stands for. Or be a project manager and never have seen MS Project in your life.
Cons
Too many overpaid - underskilled staff sitting on their behinds. First level management protects their friends to protect their jobs. Front line management does not posses the knowledge or skill sets to understand the requests or requirements being presented, they are to rock the boat. Far too many uneducated and underskilled staff that have been protected for years and now that the real world has come knocking on their door, they are scared and complaining, Where else can you have a job for 10 plus years in IT without a degree, no certifications, no skill set improvement? Where else can you complain that you cant work from home most of the week? Where else can you come to work past nine, take a two hour lunch, (two hours because besides lunch I have to exercise or play volleyball) and leave before five pm. Most of the older employees act as if it is a high school clich.
