Gerry Madden – Northern Ireland Representative & Honorary Treasurer


Gerry Madden began his social work career in 1978 as a Trainee Social Worker leading to gaining his CQSW at Aberdeen University in 1983. He is also a practicing Approved Social Worker since 1989 and obtained the Practice Teacher Award in 1991. Gerry practiced throughout the period of the conflict in the North of Ireland known as the ‘troubles’ and has many experiences of violent situations, culminating sadly in the bombing of his home town Omagh in 1998 resulting in the death of 29 people and unborn twins, the greatest loss of life in a single incident during this period.

Whilst the early part of his career was child care focused, Gerry has spent the past 35 years working in mental health services and is currently involved as an Approved Social Worker in undertaking work relating to the introduction of new Mental Capacity legislation. He has been a member of BASW for almost 40 years, joining BASW Council in 2009 and he was present at the inaugural meeting of the Social Workers Union in 2011. Gerry has served continuously on the SWU Executive since that time, also undertaking the role of Honorary Treasurer.

On a personal level, Gerry’s priority is family life including his two beloved Scottish Terriers, Lily and Katy! He is an Insulin Dependent diabetic for 40 years and has a passionate interest in Gaelic football. Living and working in a divided society all his life, he remains inspired by this quote from the late John Hume – “Difference is the essence of humanity. Difference is an act of birth and it should therefore never be the source of hatred or conflict. The answer to difference is to respect it. Therein lies a most fundamental principle of peace: respect for diversity.”

Allison has recently developed resources about her Welsh Romani family, for the new schools  curriculum in Wales and is writing a children’s fiction, to ensure that children are taught from authentic resources developed by Welsh Romani, from lived and living experience, as an active process of decolonization, inclusion and representation.

Edith Till – Student / NQSW Representative


Edith Till: I am a mature student transitioning to a new career after 20 years in the creative design and wedding photography industry. Over time, I developed a community art group aimed at enhancing community well-being through family-centred public venues. This experience, along with encouragement from professional friends, inspired me to pursue a Social Work degree.

As a disabled student, I hope to use my personal experiences to inspire both my peers and service users. Attending various Social Work conferences inspired me to apply for a Social Work Ambassador role at BASW. I involved in organising the BASW Student Conference 2023 and participated as a student panel member. I also engaged in GFTU’s education training and wrote several articles that published. Additionally, I won a trip to the Miner’s Gala, where I marched as part of the GFTU/SWU student delegation.

Currently, I serve as Class Rep for my Social Work cohort at the University of Bedfordshire and actively contribute to the Social Work Society by organising events, trips, and guest speaker sessions. Being elected to the Student Executive feels like a natural progression, allowing me to contribute to positive changes within the profession such as Disability Student and Staff support improvement. While I may have limited practical social work experience, I am eager to learn from more experienced colleagues and bring my transferable skills (such as digital design) to the role as a SWU Student Ambassador.

Innocent Sibana – UK Representative


Innocent Sibana: I qualified as a Social Worker in 2012 and worked for Dorset County Council, in Christchurch, as an adult Social Worker for 5 years. I did locum work for a year and joined Hampshire County Council, working in Basingstoke, leaving end of February 2020. I joined my current employer, Bournemouth Christchurch Poole (BCP) Council in March 2020 as adult Social Worker before assuming my current role as a Team manager in August 2023, initially at Bournemouth East Team and Royal Bournemouth Hospital as from November 2023.

I have done numerous trainings including placement educator and Best Interest Assessor. I have a keen interest in working with adults who self-neglect/hoard. Before becoming a Social Worker, I trained and worked as a high school teacher in Zimbabwe between 1993 and 1997. I was involved in the formation of the Progressive Teachers’ Union of Zimbabwe in 1997, worked in various positions in the union and ultimately became its fulltime National Coordinator in 2000.

Working as a frontline unionist in the tough terrain of Zimbabwe in the late 1990s and early 2000s, I gained a lot of knowledge and experience which can be valuable to my work in SWU. This pertains to membership building, mobilising members in campaigns/ projects meant to engender greater social justice and embedding unionism.

Rebecca Austin – UK Representative


Rebecca Austin: My learning outside of Social Work roles has been a central factor in my own development as a practitioner, both guiding and bringing me back to the core interests, beliefs and values I hold as a practitioner. Central to this is keeping in mind an understanding of how people arrived at their current position and the challenges faced by those accessing services. As a practitioner I aim to work alongside people in a kind and respectful manner, understanding that reaching out for support is a big step.

I am someone who has a love for learning about and understanding different communities and practices and have been fortunate through my role on the SWU Executive Committee to participate in knowledge exchange trips. This has included visiting Palestine in 2020 and most recently Canada in October 2023, spending time with organisations working with the First Nations population, advocating for their rights and the support offered within therapeutic treatment centres. I was particularly struck by how the values weaved through the organisations we visited, these centred around Hope, Belonging, Meaning and Purpose as a framework for practice.

Having such experiences reignites a passion for working within organisations with a clear mission, goals and values and has been a driver in my desire to most recently take a role within a third sector organisation. It brings me back to my motivations for entering Social Work having volunteered with Home-Start as a young mum myself and reminds me how inspired I feel when visiting or being part of such organisations. What I see, feel and experience is a passion, drive and inventive support for the communities and people they serve.

Scott Richardson – UK Representative


Scott Richardson has worked in adult social care for roughly ten years, working his way from administrative roles, through to completing his social work degree.

Scott has lobbied at Westminster meeting with MPs and chairs of all party parliamentary groups to advocate for the social work profession through the lens of EDI, looking at the impacts and barriers of student experiences in social work education. Scott holds a post as a student ambassador at the British Association of Social Workers (BASW) where he is leading on a co-produced EDI student experience survey to help improve the experiences of social work students. Scott is a committee member on the BASW EDI advisory group where he acts as a critical friend for BASW. Scott sits on the committee for the BASW neurodivergent social workers special interest group where he was involved in co-producing the SWU neurodivergent social workers employee pledge which was created to help create inclusive, educational, and work environments for neurodivergent students. Scott has also developed and provided workshops on neurodiversity in social work at universities, and at practice educator conferences.

Tina Peterson – Scotland Representative
