CompuCom is bad.
CompuCom is a terrible company to work for. The management thinks it's funny to come down and threaten someone's job on a nearly daily basis, there's a constant threat of being terminated, the pay is poor for how much work you have to do and, even if the people who work there are fantastic, there's an oppressive air of fear and hatred.
Though SunCor is far better, using CompuCom as an in for them isn't a bad idea. If you can tolerate the place.
