Pros
The only pro I can think of is that I enjoy working with the people in my office and on my team. If it wasn't for the people, I wouldn't have stayed as long as I have.
Cons
No work/life balance No real salary increases Management expects you to work over time as the norm, not the exception. No room for advancement There is no training or real support The business units don't work together to promote "one Fiserv" Internal groups are always fighting with each other and not working together to support the clients Management does not work together to help alleviate the issues that we are experiencing There is more emphasis on hiring sales people and account executives to bring in more business, but no one considered what the additional business would do to the teams that have to do the work. There was no additions to staff, and now we are in a place where it is practically impossible to keep up with the work and provide good service to our clients.
