Pros
3M offers competitive salaries, pretty good benefits, generous PTO, and tuition reimbursement. They have dozens of "after work" clubs you can join. If your manager cares, they will invest in your career. They try to be active in the community, volunteer with or donate to several non-profits, and have programs for young students and college interns. Before they switched to flex work, they had farmer's markets on campus and food trucks every Thursday. They had celebrations on campus for dozens of holidays from all cultures. It really seemed like they valued their employees and tried to keep them happy.
Kontras
In September 2025 they ended their flexible work policy and are requiring employees to return to office. Raises each year were around 2%, and the Annual Incentive Plan is included in your salary - so if you or the company don't meet expectations you will not receive your full salaried amount. During my years there, they had several large global layoffs, sold off a few product lines, restructured several times, and then their healthcare business split off. The enterprise culture was very hierarchal, so individual contributors were not active in decision making. I often went unheard or undermined. Senior leadership felt disconnected from their business groups. There was an informal rule that you did not go above someone, even if something needed to be escalated. They drilled the Ethics policies into your head, but they didn't seem to follow them. I had reported a coworker for sexual harassment, and another for bullying and retaliation, but HR did nothing. I was advised to quit, but I was lucky enough to just move teams. And their EAP is not confidential, as so they claim. There were several employee clubs or internal organizations that represented minority groups, but they didn't seem to have an impact on company culture. For example, when I worked there, the Women in STEM leadership team was all men.
