      Pros

      Many positions and room for growth within Chicago. Culture is very focused on Associate Development.

      Cons

      Wrigley campus is not close to downtown, and inconvenient for suburban commuters. Declining Gum business has been driving lean staffing and numerous restructures over the past 18 months.

      Pros

      Great people who believe in a common mission. Strong leadership and support.

      Cons

      Budgets and decision making for technical programs are centralized at a high level with little to no consideration for how it affects individual programs and their unique needs. Heavy bureaucracy involved in setting up simple things.
