Thank you for taking the time to share your perspective. We are glad you experienced flexibility in daily work and opportunities to broaden skills through cross training. The concerns you describe around leadership behavior, fairness, and the impact on well being do not align with what our company stands for. While we cannot address individual situations here, we encourage anyone who experiences or witnesses misconduct to raise it through HR, management, or our confidential SpeakUp channels so it can be reviewed appropriately. As you are no longer with our company, we appreciate the feedback and wish you all the best for your next steps.

Pros

Good pay, benefits, and time off.

Cons

No work life balance whatsoever. This job has been awful for my physical and mental health purely due to stress. Long hours with schedule changes frequently, management not understanding the needs of junior level employees, and hazardous working conditions are often a problem. Coworkers can be friendly, but everyone is put through such stress that there are a lot of conflicts between everyone. People are very competitive and often tend to look out only for themselves rather working as a team.

Thank you for sharing this — we recognize it takes courage to speak openly about experiences that have affected your health and well-being, and we want you to know this feedback is heard. Compensation and benefits should never come at the cost of someone's physical or mental health, and the picture you describe — long hours, frequent schedule changes, hazardous conditions, and a high-stress team dynamic — is something we take very seriously. Feedback like yours is important in helping us understand where there is room to improve. On the topic of hazardous working conditions specifically: we encourage you to report any safety concerns through your local EHS (Environment, Health & Safety) contacts, as these warrant dedicated attention. As a current employee, your voice carries particular weight — and we encourage you to share your experiences in our Employee Opinion Survey as well. It is one of the most direct ways to help shape the direction of our workplace in a structured and meaningful way. We hope things improve for you, and we remain committed to listening and to fostering an environment where every employee feels safe, respected, and valued.
