Pros
This may be the safest company to work for on the planet. Safety is a serious issue with ATI, and is the number one core value. This is a company that wants you to leave in the same condition that you arrived. The 401k company match is well beyond most employers. Sick day policy is very modern and in touch with the current times. Flexible working hours are generally available, although not the official policy.
Cons
This is a "what have you done for me today?" IT culture. IT is viewed as overhead, not an asset. Raises are consistently below the cost of living. Bonus is average. No stock options for staff. No employee stock purchase program. The reward for working hard is more work. Additional responsibilities and the option to lead projects and learn new technology to add value to the business is rare. No formal way to obtain training. Health care seems to be high for what is covered. Vacation policy is not very current. No on-site gym or cafeteria. Standard beige office cubicle farm. Too many office politics. Excel seems to be the most valuable IT skill.
