Why do you work in the Wellbeing field?
Affinity Health at Work was born in 2006 with an aspiration to partner academic rigour with practical, real-world approaches to improve health and wellbeing at work. With our team at Affinity, our clients and our research partners, I strive to develop solutions that make a difference to peoples' working lives, which is what makes working in the wellbeing field rewarding for me.
My work is driven by three things:
First, everyone has a right to well-designed and well-managed work; work that is safe and allows people to thrive, where people are recognised for their contributions and supported by others when times are challenging. We are not there yet but whichever way you look at it – with a moral, legal or business lens - it makes good sense.
Second, evidence is at the core of all we do at Affinity – creating evidence and using evidence to guide solutions. There is so much noise in the field of workplace wellbeing that it can be hard to know what to do for the best. We look to the evidence to guide us on what works, and what doesn't in different situations, and our vibrant research programme means that we are creating and sharing new evidence for all, all of the time.
Third, no one can do it all on their own. Everyone needs to be supported at home and work to stay well and do their best work. This is why we look beyond the individual and take a whole-system approach to wellbeing – understanding the individual, the people they work with, and the organisational and national context in which they work.

Dr Rachel Lewis;PhD, MSc, CPsychol
Managing Partner
Rachel provides the leadership and direction for Affinity, alongside Jo. Rachel is widely published in the field of health and wellbeing at work and has contributed to national guidance, and evidence-based tools and interventions. She also leads on strategy development, risk management and training and development programmes.
Why do you work in the Wellbeing field?
The wellbeing field has come a long way from where it once was, particularly in response to the global climate in recent years, but we still have quite a long way to go before we see job design that is truly shaped to support and protect the wellbeing of its workforce.
Over my career I have seen, and continue to see, many wellbeing approaches taken within organisations that evidence suggests will have no meaningful impact. This has really solidified my stance that evidence-based practice should be at the forefront of my work, to ensure the quality and effectiveness of every wellbeing policy, intervention or guidance that I produce.
I have brought this principle of ensuring evidence-based practice with me to Affinity, and I am very proud of the company Jo and I have developed. Affinity works on this principle and it has become a core component of our work to ensure that any solution we recommend to organisations is sound, and that it has actual tangible benefits to the workforce.
We recognise that there cannot be evidence-based practice without the evidence itself, so Affinity strives to also produce pioneering research that expands the knowledge of our field whilst providing guidance for what best practice looks like. I am very proud of the contribution we have made to the evidence base and how it has allowed us to make a difference in the lives of employees across the globe. This is what continues to drive me.

Why do you work in the wellbeing field?
The importance of individual health and wellbeing at work as well as a wider organisational culture with a focus on wellbeing has interested me throughout my time in consulting and one to one coaching.
Over the last few years I have developed an interest in the area of positive psychology, and the scientific research into practices such as gratitude, resilience and compassion and the impact of those practices on wellbeing and their integration into organisational culture.
I am fascinated by the role that work can play in the health and wellbeing of individuals and in turn how the thriving of individuals collectively can lead to the success of an organisation.
I am excited to partner with organisations at Affinity, to design and implement evidence-based solutions that help their employees thrive at work.

Why do you work in the wellbeing field?
Work is a fundamental part of daily life for so many of us for the majority of our adult lives. Your physical and mental wellbeing at work can have significant impacts on both your success at work and on the other parts of your non-working life.
