Pros
When the company was metavante, employees were valued. Promoting from within, retaining employees, and open employee collaboration was the main focus. The teamwork between diverse departments, prevented client outages. Metavante was tuned like a swiss watch. A typical employee could be woken up, in the middle of the night, to help out anyway they could. It was this ethic, that I too emulated. When FIS took over, many valuable "gurus" were let go. The tens of thousands of experienced hours went with them. This caused, the other employees to wait for an economic upturn to exit, which they did. This combination of voluntary exits and yearly "reduction in workforce" has left FIS in shambles, with constant client SLA's triggering loses for the company.
Cons
If you are a company, that FIS has just acquired, leave asap. FIS will diminish a person's work ethic to the point I could not wait to be let go with a severance. This happened and I"m very happy with the outcome. FIS reduces staff while increasing workload disproportionately. FIS manages by fear and micromanagement. A co-worker stated the new FIS ethic perfectly, and I quote "I've never worked for a company that despised it's employees". I agree.
