Pros

Fellow coworkers are nice. The products are interesting. The market trend for Mirion is going up. Nuclear industry growth in the future with SMRs.

Cons

Low pay for detector production workers and techs. The company does not promote people the way all other companies do. Most companies promote based on yearly reviews and performance, but it appears this company only promotes if you try to leave, or complain to the right people. Management literally has no idea what your background is, what work you do, or how much, and they don't seem to really care. The company typically hires new people externally than promote internally. New employees getting paid more than ones that have been here for years. Very high turn over rate. Rude management. Bonus system has been reduced. They used to have farewell retirement parties and promotion parties for employees in celebration, they don't even bother sending emails out about either anymore in Detectors. Management keeps rushing detectors out the door, constantly skipping several parts of the testing QA, and ignoring clear signs of failure to meet quotas. People that get hired leave relatively quickly.

Pros

Great teamwork and collaboration. Professional colleagues. Clean buildings/work environment. Good work/life balance.

Cons

Work/Life balance seems to be shifting and not in a good direction. Lots of uncertainty as a managed service provider was brought in resulting in many people being blindsided by lay-offs. Overall morale and culture moving in the wrong direction since layoffs began.
