Academic Expertise

Ffyon took an extended period away from practice as a lecturer in law whilst raising her young family. She is therefore comfortable on her feet and in writing. Alongside lecturing in law and academic writing, she created a large number of clinical legal education partnerships with NGOs and social enterprises such as Appeal and Reprieve. During lockdown, Ffyon built and led volunteer teams of lawyers and students, delivering legal advice and services through virtual and hybrid clinics and supporting NGOs with research and policy work. This also offered future lawyers’ meaningful case‑management, advisory, drafting, and client‑engagement experience when opportunities were in short supply, equipping them with the skills and experience they needed to move forward in their careers.

She is published in New Law Journal, Counsel Magazine, FT Publications and contributes biennially to a major law textbook.

Notable Employment Cases


Jasim v LHR Airports Ltd [2024] ICR D31

In Jasim v LHR Airports Ltd, Ffyon represented the successful appellant at the Employment Appeal Tribunal (unled). The appeal concerned claims of trade union detriment and whistleblowing. This was the first case to substantively apply the 2023 amendments to the Employment Appeal Tribunal Rules and Practice Directions. The court’s decision provided important clarification on how procedural errors should be managed under the amended rules, particularly regarding the extension of time for appeals. This case offers new judicial guidance on balancing procedural compliance with fairness in employment law appeals and the application of the Civil Procedure Rules to Employment Tribunal rules and directions.
