Pros
Many can work from a home office.
Cons
Subject Matter Experts retire, leave the business for greener pastures, are RA'd (Resource Action, permanently laid off), or die at their desks, their work load heaped upon those left with little or no training, documentation or resources. The 40 hour work week does not exist. Sixty to eighty hour work weeks with 3 hours of sleep between shifts is not unheard of. Peers lob hot potato and hand grenade work orders to you with little or no guidance and run, leaving you with no way to get the job done in the required time frame. No funding available to upgrade internal processes to the levels sold to the customer. No funding for anything. Abusive employee ranking system (PBC) never reflects the quality of your work, just the required bell curve. Good work not rewarded with pay raises. If I had a golden parachute I'd jump now and pull the ripcord.
