And most importantly we value every individual’s wellbeing. As a diversity champion, equal opportunities and disability confident employer and an ardent advocate of flexible working we understand that everyone has unique requirements and needs. We are a global creative agency, but the individual really is at the heart of everything we do. We use data to find out what makes them tick. We use technology to talk to them one-to-one – but to one million at a time. And we use creativity to encourage them to engage, click, buy and bond, again and again. Each brand is unique and has its own individual challenges. We pride ourselves in rising to each and every one of them, for brands such as KFC, Mercedes Benz, IKEA, Paypal and Virgin Media 02. UsWe are true advocates of flexible working with a hybrid working policy of 3 days per week in our incredible South Bank office, next to cultural hubs such as the Tate Modern. We ask you to work where and when you work best. We’ll be honest though, we do love seeing people in the office, because it delivers on our Culture, Collaboration and Connection. For Concentration, work where you’ll work best. We call it the 4 Cs.Learning and Development is important. We all know that. Its why we have a dedicated Learning and Development team and offer regular career conversations and bespoke L&D programmes so that you can leave us with more than when you started.We recognise that the work of diversity, equity and inclusion calls on all of us. That’s why we set up The Neighbourhood. A collective of people, at different stages of the DE&I journey, whether impacted or allies, dedicated to helping our colleagues take ownership and effect change across 4 key pillars; Anti-racism, Disability, Gender & LGBTQ+ and Parents & Carers.The Health and Wellbeing of our people matters immensely. We offer Coaching opportunities for all through our partnerships with Sanctus (mental health partner who provides online coaching; you can talk about anything, personal or professional) and Sayge (1:1 professional development coaching program). We have 40 trained Mental Health First Aiders across the agency and have Babylon Health (Private GP service) for all.You’re better at work when you feel better in yourself. So, in addition to your annual holiday, you can take a “Me” day and an “Us” day, every year. Your “Me” day is for you to invest in yourself – go after a life goal, meditate, learn to paint, bake cakes or just have a duvet day watching Netflix!Your “Us” day is all about giving back and helping others – volunteer, pick litter at a local park, hang out with the elderly or raise money for a local charity. We’re progressive and always open to new initiatives, for example we’ve recently partnered with Fertifa (Leading Fertility and Reproductive Health benefit providers). Because we know the journey to becoming a family isn’t always easy (that includes men too), and we support our people through that journey whether you are new parent, experiencing the menopause, or anything else in between.Whatever stage of life you are at, we make sure you have the tools you need to have a healthy work life balance.Recruitment processWe like to keep recruitment swift, lean, and individual and find that 2 or 3 stages gives all parties the opportunity to get to know each other. Plus, we have a team on hand to answer questions throughout the process.We are RAPP, and we can’t wait to meet you!
