Thank you for your feedback and for highlighting what makes your experience meaningful — working with great colleagues and the opportunity to take on varied assignments are aspects we genuinely value and aim to foster. On our MyGrowth platform, we would encourage you to explore the career options and growth assignments it offers, including temporary full- or part-time moves into different departments — it can be a valuable tool for shaping your path within the organization. Regarding accountability, structure, and cross-regional alignment, we hear you. Clear decision-making and well-understood responsibilities are essential in a global organization, and we recognize that consistency across geographies remains an area of ongoing focus. We encourage you to raise concrete examples with your manager and to use our annual Employee Engagement Survey to share your input — this is how we identify where leadership practices and processes need to strengthen. Thank you for sharing your perspective as a current colleague.

Thank you for sharing your experience as a current colleague at our Burlington site, and for the positive recognition of our benefits and work-life balance. We hear your comments on organizational silos and career path clarity. Navigating a large and complex global organization of our scale and history can sometimes make it harder to see the full picture of where your career can go. We are actively working on further reducing silos and improving cross-functional visibility. On career development, we encourage you to explore the opportunities available through our MyGrowth platform, which is designed to help employees identify growth paths, development assignments, and new opportunities across the organization — including temporary or permanent moves into different teams or functions that may not always be immediately visible from within your current role. We also invite you to share your perspective through our annual Employee Engagement Survey, where input like yours helps shape how we evolve our ways of working and career development frameworks. Thank you for your continued contribution — we hope your journey with us continues to grow in the direction you aspire to!

Thank you for highlighting the benefits and our PTO offering. We also note your experience regarding career progression. Growth opportunities and transparent development conversations are important to our company, and we encourage employees to discuss aspirations and next steps with their manager and HR, and to use tools such as MyGrowth to make expectations and development plans visible. Your feedback is helpful as we continue working to ensure fair, clear processes for internal moves and promotions - as a current employee, we invite you to share these observations in our annual Employee Engagement Survey (EES).
