My 3 years experience working for 3M. - Administrative Assistant 3M Employee Review

Large Corporate Network Interesting Products Good company culture

Technical employees see fewer/less frequent promotions

Stable income and benefits, and a decent campus.

Sometimes not as much room to move unless you're in with the right people. I say it's stable, as in income, of course, till there is a bad year and your division/buisness group is on the chopping block. No real incentive to overachieve.
