      Pros

      Relocation bonus, hired moving company, 3M name and recognition, interesting work and products, free Lean Six Sigma training

      Cons

      O2 requires training commitments that somewhat interfere with job responsibilities, must commit to two one-year rotations or pay back 100% (<1 year) or 50% (<2 years from last move) of relocation expenses, mostly engineering not EHS or supply chain focused

      Pros

      Good pay and decent benefits.

      Cons

      Current management is completely disconnected from the needs and concerns of individual contributors. Which appears to be on purpose, as the company is in an active strategy of both strategic layoffs and of driving attrition in general, so everyone's stress levels are super high. The head of HR just quit so I can only assume worse labor actions are on their way. Also, be ready to not have a desk but still be required to come in 4 days a week.
