Pros

In my opinion, Mirion is a great stepping stone to obtain either research or industrial experience that later on gets you a job that pays much more. Mirion in my opinion is not a 'forever job' In my opinion the atmosphere in some spaces are open for new ideas and solutions. The company does a lot of kaizens and Continuous Improvement, though I don't see many changes as a result. They have little food-truck events or yearly Christmas parties or picnics for employees. Cafeteria with breakfast and lunch every day for purchase. Snack bar with drinks and snacks for purchase. Company will try an make an counter offer if another company tries to hire you, showing they will fight for you. The technologies are very cool and it is all very fun to learn about. Each department's directors and management are easy to talk to and they want you to succeed. Has program for paying tuition if you continue schooling for work.

Cons

I don't like the pay especially for jobs that are requiring a STEM degree. The work instructions appear old and outdated compared to the actual work processes. Managers seem disconnected from lower level workers. They used to offer certificate trainings for things like soldering but that halted a few years ago. They used to have a pretty good production bonus but they lowered it to cut costs. Its difficult for departments to get approval to approve replacement positions for those who leave, causing positions to have no backfill or training. It's hard for department heads to get approval for budget and raises for their employees, causing a lack of upwards mobility. They used to have a performance-based luncheon system that they removed. It appears difficult to receive promotions despite receiving great managerial reviews, this is likely caused by the fact that all promotions need to be approved by corporate. In my opinion it appears that management does not know the background or skills of their employees Corporate management is entirely detached from production management. As a public company, corporate only cares about increasing profit for shareholders by increasing production and cutting cost. In my opinion, they are doing this backwards. They are cutting costs by cutting employees, pay, and benefits of production facilities which is in turn hurting production. Corporate is urging general managers to cut costs by any means. Job security is at risk, and job advancement is practically nonexistent, despite how hard production directors fight for it. Corporate meanwhile is filled with so many VPs, managers, and directors, that it's hard for the produced cash flow to go anywhere else. The money is not reinvested into the cash producing factories or employees, it is used to further expand the overhead corporate structure, which cannot entirely prove the need for it's existence at this size. As the money is not reinvested into the production facilities, production does not grow. Which means the only way to make more cash flow, is to cut cost from those very same production facilities (as the corporate structure will never cut cost from itself). This causes our production facilities to be working too thin and lean, starving off the experienced workforce, and being unable to train replacements.
