Pros
3M has a history as a great place to work. The past culture of the company has been such that you can go into a 3M office anywhere in the world and feel at home. This culture is morphing and, paired with a number of business challenges, makes 3M not such a fun place to be in 2022 / 2023. The company is trying hard to fight the litigation it faces and to spin off its Health Care business. If it can succeed on both of these fronts, I'm sure there will be brighter days ahead.
Cons
The company is turbulent at this time (2022). There is a very heavy focus on the short term that has become so extreme, teams cannot even complete the last short term decisions before direction is shifted again. I started in the early 2000's and at that time, I spent about 60% of my time as a strategic thinker (fresh out of undergrad). As time went on, this became less and less of a focus, even as I grew in my career. Trying to wrestle leaders into strategic planning was generally met with deaf ears. Now, there is zero oxygen for long-term planning, at least within my function.
