Pros
Most of the line level people I worked with were nice. There are some genuinely skilled and talented people working there. Salaries are generally good and is the only reason I don't rate it as one star. Benefits used to be better when it was just Safeway but since the Albertsons acquisition the benefits have become decidedly average.
Cons
Management is atrocious. 1950s management style is pervasive. Work from home is discouraged. Flexible work schedules are discouraged. Internal processes are rigid, inflexible and outdated. Management pretends to listen to concerns but does nothing about it. IT infrastructure is dominated by creaky, expensive, ancient mainframe systems. IT is seen as a cost center not a center of innovation. Contrast that with successful companies like Amazon where IT is a key player and they actually invest in IT. Company is shouldering an enormous amount of debt which limits their ability to compete with the likes of Amazon (via Whole Foods) and WalMart. Stores are closing left and right and management has no answers to compete in the modern business environment. In IT you will learn lots of useless non-transferable skills. If you are looking to build skills in anything developed in the last 10-15 years this is not the place for you. Culture is a passive-aggressive political minefield. Navigating this quagmire is rewarded with promotions and bonuses. True leadership and accountability will get you marginalized.
