Meet the Team
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.
