Avantages
Fiserv isn't hiring in this area. You won't have time to spend the salary you make because they expect you to work whatever hours they choose and those can change at a moments notice. The stress placed on employees is a great way to lose weight, I have personally lost up to 40 pounds in a year.
Inconvénients
Management is dishonest. When you are able to prove that they have made a mistake they will try to place the blame on someone else. The business environment is manage by intimidation and employees are constantly threatened with "disciplinary action up to and including termination". Harassment complaints are not investigated. Employees are routinely called on vacation days and although the company policy is to give those days back, you have to fight to get them. New employees are routinely hired in at more than current employees salary.
