Pros

They actually allow advancement from the bottom. OSH is one of the major outlets for Lowe's growth plan which means there will be a steady path for advancement for years to come.

Cons

Nepotism, and racist favoritism have been regular. You'll go further faster if your female and Hispanic. I've been passed up once by someone who was marginally less competent and once by someone who is almost completely incompetent. Both were Hispanic females. One white person has been promoted above the Department Lead level in the last four years out of four opportunities. So 25% of major promotions go to whites while 82% of the population is white.
