Pros
For your immediate team, the people are excellent almost tribe like. If you have put in enough time you will have a strong team.
Cons
There is no opportunity for advancement nor promotion unless you live in 2 particular cities for IT people. The company will not invest any resources or capital to ensure good workers remain, or continue to advance, learn and grow unless you live in those 2 particular cities. There is no flexibility for family time for anybody in IT in SCS. There is an unstated expectation you should be able to continuously work 60+ hours a week without stopping all year potentially. Work weeks are regular 60-80 hours if you let it happen with no respite nor comp days. This is not possible for any human long term. They get torn down. There are not enough "technical" people/resources being hired to take up slack or help with infrastructure and software IT responsibilities across the board. Contractors will not be kept after a certain amount of time even though they gain a lot of knowledge and become valuable to the teams they work with. The management of software and hardware updates is always done in a frantic, fire fighting mode after the lead time to act has already past because there is not enough technical people around. The bigger parent company, UPS, with many more resources always takes precedent and expects SCS to magically have the same capacity to update all their systems in the same time frame they do.
