Pros

Built many solid relationships with a lot of really great people. Spent 12 1/2 years in an industry that I loved.

Cons

Senior leadership will do whatever it takes to cover their own behind. I was told by my manager that I could use my PTO and have flexibility instead of using company sick time, and have it documented on numerous occasions. However, I was let go due to “attendance” after 12 1/2 years of loyalty to the organization. When I was let go, I had used 6 sick days for the year. Manager asked me about a technician who had falsified data, asking what I would do. I told him that data falsification is something you should be terminated for. The technician in question still has her job. Saw senior leadership stop caring about people. It turned back to profit, and employees suffer. Delayed merit increases. Missing huge blocks of time having 1:1’s with my boss. My managers wife is a current surgeon at the site and is a notorious bully. Constantly talking about people behind their backs, criticizing anyone who isn’t like her, being rude, etc. We lost an experienced supervisor because of her who couldn’t take her anymore. She’s still there, shocking! Company stopped regular 401k matching, saying that they would pay it out at the end of the year instead. So, if you get let go or leave, you lose the years match. The little bonus that folks do receive was reduced by nearly 70% in 2025. Politics plays a part in advancement and respect. It’s not about your work, it’s about who you know.

Pros

The people you work with under the leadership level are great and truly try their best every day to do the best job they possibly can.

Cons

Everyone is severely underpaid for the amount of work they’re expected to do. People will quit/be fired/laid off and no additional help is provided. Those who remain are expected to pick up all of the slack. Leadership is variable on the day-to-day but you never truly feel supported or like your problems are taken seriously enough to resolve. Individuals are actively urged not to present counter job offers as a way to negotiate higher pay or a different position because “the site head doesn’t like it”.
