Pros
I have been with TSYS just over ten years now, and while they certainly have issues (just like every other company out there), overall, I have been very satisfied. They executive management truly cares about the employees and the success of the company as a whole. The beneftis packages are fair; not the best I've ever had, but certainly better than most. The company is also very flexible as far as work locations and schedules which is extremely valuable to me personally. TSYS also has an eye toward the future, and is doing everything it can to stay viable through innovation.
Cons
Let's just be honest, nobody is ever going to think they make enough money, and everybody thinks they deserve a promotion. TSYS pays fairly, but they are not going to make you rich most likely. There is a lot of competition for promotions and pay increases, so you're not going to fly up the company ladder like you could potentially do with a young, upstart company. This is an established company, and you're going to have to be patient.
