Susanne Matthissen (Capital Law)

Susanne Matthissen

Senior Associate
Employment & Immigration

Susanne is a Senior Associate in our Employment and Immigration team. She advises on both contentious and non-contentious aspects of employment law, as well as all aspects of information law, including the General Data Protection Regulation (GDPR) and Freedom of Information Act.

She advises a range of clients from individuals to family owned businesses and third sector organisations, local authorities and large private companies.

Susanne undertakes employment aspects of corporate transaction work, including employment due diligence, drafting employment contracts, director service agreements and consultancy agreements, advising on TUPE and the employment related aspects of the transaction documents.

As well as our work with employers, Susanne is also involved in advising individuals. This work includes advising individuals on disputes in the workplace and in employment tribunal claims, which includes guidance on disciplinary and grievance processes, negotiating exit packages and legal advice on the terms of settlement agreements.

Susanne assists both public and private sector clients in advising on their legal obligations on information law legislation and providing practical assistance in relation to any requests made under GDPR and FOIA.

She can also help with information law compliance planning and implementation, undertaking data audits, as well as designing and delivering workshops and bespoke in-house training for clients and their staff in relation to GDPR and FOIA.

Susanne also attends Cardiff Employment Law clinic to provide Pro-bono advice to individuals that need help, as well as attending the Employment Tribunal Litigant in Person Support Scheme to provide unrepresented litigants with initial advice and representation at Cardiff Employment Tribunal.

Probably the most useful professional training I’ve ever been to – not an exaggeration. We need this kind of practical information. You’ve hit the spot!
