Pros
3M is the third company I have worked for and by far it is the best! I have had more than ample opportunities to advance my career and I have been very happy in the autonomy I have in how I do my job. Overall the people have been excellent and leadership has been good. I hope to work here as long as they will let me. My management has been very supportive of my advancement and has worked to help me move up. Great pay, competitive benefits.
Cons
Over the past ten years the company seems to have gotten more bureaucratic with more and more mandated corporate programs. Frankly these have not added much value. Also the blessing of having many long term employees is also a curse. Many are complacent and become negative about how bad they have it when in reality they have it better than 99% of the population out there. My only worry is that over the past few years company growth has been a challenge. We have been able to cost control our way to meeting earnings expectations but that next big thing has. It been visible and I am worried that eventually investors will lose their patience and force management to do dumb things.
