Flexible Working

At Omnicom Media Group, we are committed to supporting flexibility for our people while fostering collaboration, innovation, and teamwork. We have a hybrid working model (three days in the office, two working remotely), to ensure that we meet the needs of both our people and our business, balancing the benefits of in-person connections with the flexibility of remote working.

Our standard working hours are 9:30 – 17:30, but we offer the ability to flex around core hours of 10:30 – 16:30 to give our people flexibility on how they manage their working day, whether that’s in the office or working remotely. For example, you could start work at 8:30 and finish at 16:30 or start at 10:30 and finish at 18:30. We encourage open conversations between our people and managers to help navigate high-need periods and individual circumstances. Our goal is to create an environment where people feel genuinely supported to do their best - both in their careers and in their lives outside of work.
