Being an in-person business

We're at our best when we're close to customers, and for many of us at M&S, that means working in store every day.

To stay close to customers, our support teams are in the office three days a week as we believe that skills are developed through collaboration, and that spending time together makes us more creative and connected. It also means we can solve problems as soon as they arise, learn and grow as a team, build trust, and get closer to our colleagues.

What motivates me is getting to learn something new, and the best thing about buying is that you can go into any area, and you’ll become an expert in it. I started in food – ambient snacking and soft drinks – then moved into homecare, buying pet food and household products. Now I’ve been promoted to a Senior Buyer role within our Bakery team.
