Pros

Strong community, knowledgeable operators, operations schedule

Cons

Management. They are constantly unprofessional and bully everyone. A lot the engineers and supervisors quit because of this. A few of the ones that left really cared about the plant but couldn't stand the constant yelling, cursing, and name calling that take place from management.

Thank you for taking the time to share your feedback and for your contributions over the past several years. We’re glad to hear you value the strong sense of community and the expertise of our operations teams. Those are important strengths we aim to maintain. At the same time, we take your concerns about management behavior very seriously. A respectful, professional work environment is a baseline expectation, and what you’ve described does not align with the culture we are committed to building. Feedback like this is critical in helping us identify where we need to improve. We are actively working to strengthen leadership accountability, reinforce expectations around workplace conduct, and ensure employees feel heard and supported.

Pros

Even as an employee that was let go, I can’t say anything but very positive things about Delek US’s corporate office, refineries and terminals! Great coworkers and mentors to learn from. My advice: BUY THE STOCK!!!!

Cons

Constantly improving which can be challenging at times, but usually for the best… It’s the oil industry!

It’s great to hear this perspective, especially from someone who spent several years with the company and is speaking positively even after leaving. That says a lot about the people and culture you experienced across the organization. Strong teams, mentorship, and opportunities to learn are things we continue to value and invest in. We also appreciate the recognition that continuous improvement can be challenging at times. In a dynamic industry, that mindset is critical, and we’re always working to balance progress with supporting our employees through change. Wishing you all the best in your next chapter, and thank you for the time and contributions you made during your years at Delek.
