Pros
Safeway is a large, generally very stable company that offers a wide variety of positions in many different areas to try. It is also a company that promotes from within, and presents internal opportunities at many levels. It is a successful Fortune-60 company that will be around for years to come. Safeway is also a socially and environmentally conscious organization.
Cons
Safeway has been in the retail business for a long time and it shows. A good amount of people working there have been doing so for many years, and 30-yr veterans are not uncommon. The benefits package is a bit outdated (with a pension plan, and no 401k match), and many of the policies are consistent with what you'd expect to see 10-20 years ago. Safeway's management does not focus much energy on providing a work-life balance, and the way people conduct business is very old-fashioned. Generally, the environment is siloed and non-collaborative, with senior managers holding their particular areas very close.
