    Simon Walsh, from our electrical team, captured something important in this clip. The real strength of our culture comes from the way people show up for each other. When you can walk into a manager’s office without hesitation, ask for help without second guessing it, or take a moment to breathe on a tough day and know you’re supported, the work gets better, and the people do too.That comfort carries into the small moments. The quick check ins. The friendly conversations that break up a busy afternoon. The kind of day-to-day interactions that make it easier to do great work together.It’s simple. Respect, trust, and genuine connection make a difference. And that difference is why our team works the way it does.#EngineeringExcellence #YGK #LDNont #KWawesone ...
