Pros
Many opportunities to move into other jobs for especially sales, marketing, business, chemists, and engineers. Diversity of projects and people. Culture of innovation is still around. Most employees are happy to work at this company because of interesting projects and advanced technology. Very few employers have the breadth of knowledge available to the 3M community.
Cons
Innovation has taken a real hit. Creativity is stifled by management who only sees one quarter ahead. Not willing to take big risks for fear of failure. The "old 3M" which means something different to everyone really never existed, but the reason it keeps coming up (how things were better at the "old 3M") is because there has been a slow decline over many years in terms of project resources, benefits, management communication to employees, and creativity.
