Thank you for sharing your thoughts. It's good to hear that you had supportive colleagues and managers during your time at MKS—We win as a team, and those day-to-day relationships matter a lot. We also hear your concerns about compensation and feeling valued. That kind of feedback really matters to us. Every year, we run an employee engagement survey followed by focus groups so we can listen more closely and figure out where we need to do better. These conversations help shape the steps we take, and we always encourage employees to speak up and be part of that ongoing effort.
