Our ways of working

We’re a flexible-first organisation, because we know people do their best work when they have choice and clarity. To support meaningful collaboration, we ask everyone to spend at least eight days a month connecting with each other in person.

That doesn’t just mean time in the office – it could be team meetings, offsites, volunteering days, cross-functional projects, or away days. What matters is making those moments count – so when we come together, it benefits everyone.

Accessible, inclusive and equitable for all 

We believe a better tomorrow starts with the choices we make today. That means moving the dial on diversity, building equity into everything we do and putting inclusion at the heart of our business.

Virgin Media O₂ is an equal opportunities employer and we work hard to remove bias and barriers. We want every person who joins us – and everyone thinking about joining us – to feel seen, heard and supported.

When you work with us, you’ll have access to our award-winning employee network groups. These communities bring people together, champion allyship and create uplifting spaces where you can learn, share and feel part of something bigger. They play a big role in helping people feel connected from day one.
