Pros
Lots of good benefits and opportunities are available at 3M. Bosses are usually hands off (perhaps because they are so entangled in meetings). It is a great company to work for, as there are a ton of extracurricular activities outside of work hours. The company has a good pay/job grade system that allows fair transition from one job grade to the other, and fair annual rate increases, based on job grade, EC&DP evaluation and goal accomplishments. It is also a great opportunity for employees to be able to be part of a profit-sharing benefits package. However, most of all, the best reason to work at 3M is the ability to buy Post-It notes at cost, besides all the tapes and other products 3M makes.
Cons
3M, which comes from M M M, stands for "Meetings, Meetings, and More Meetings". Hence 3 M's. Every day passes with at least a meeting or three - pun intended! There are so many policies to work around, that it becomes sometimes impossible to accomplish a job in a given time frame, or worse, a project that may have required 1 month, takes 6 months to a year to complete. This slows down the momentum. The fact is that this is how ALL 3M businesses operate; it is not only a certain group, but from Operations, to R&D, to Engineering... One other downside, if you don't like to work for a "big company", then 3M is a BIG COMPANY spread around the world.
