ABOUT US
Catherine Jackson
Catherine is the Managing Director and Head of Employment at CSJ Legal.
She provides clear and strategic advice to both individuals and business clients, covering the whole range of employment issues from early stages of dispute resolution right through to Tribunal proceedings. She also has experience of supporting litigation at the Employment Appeals Tribunal, Court of Appeal and High Court.
Prior to setting up the firm she spent three years as a Consultant Solicitor at specialist employment practices in the South West region. During this time she had sole-conduct of a high volume of cases, predominantly for employees, including some high-profile and multi-week Tribunal claims against private companies and public sector bodies. She also successfully defended a number of litigated claims for an SME client.
Prior to that she worked at Associate level at a Top 50 firm in the Senior Executive team and as part of a small, dedicated team of litigators for a large international employer, as well as on retainer for a range of SMEs.
Catherine's specialisms include all types of discrimination and whistleblowing. She spent a number of years at London legal advice centre ‘Protect’ advising a large volume of individual employees and businesses on complex whistleblowing cases and supporting organisations to implement effective whistleblowing arrangements.
Catherine is a law graduate from the University of Bristol and also holds a Masters degree in Human Rights from UCL. She spent several years practising immigration law both in the UK and New Zealand before specialising in employment in 2012. She served as Deputy Chair on the Board of Trustees for Bristol-based charity Project MAMA.
At CSJ Legal our passion is driven by the ability to assist and support clients through what can be a challenging time. We believe that individuals should be fully advised of their options and empowered to challenge unfair treatment and employers should be proactively supported to embed effective arrangements and strive for best practice.
Catherine always takes the time to listen and properly understand her clients’ needs, offering clear no-nonsense advice and establishing strong professional relationships. Clients value her efficiency, personable approach, and tenacity, as well as the fact that she is a calm and effective negotiator with an eye for detail.
When not at work Catherine enjoys travel, live music, yoga, long walks in the Wye Valley and good food.
