I advise multi-national and UK employers on all aspects of UK and Irish employment law.

My clients are mainly from the technology, healthcare and the financial and professional services sectors. I helped establish our Dublin office in 2018 and work closely with colleagues in Dublin and Belfast to provide clients with employment law support across the whole of the UK and the island of Ireland. I have been recognised for many years as a leader in the field of employment law by the leading legal directories.

My practice is often international in its scope and I regularly advise on the employment law aspects of global acquisitions and multi-jurisdictional restructures, particularly across the EMEA region. I am also responsible for a number of international retainers which enable clients to access expert employment law advice in all of the countries in which they operate.

Examples of my recent work include:

  • Successfully resolving High Court Injunction proceedings in London and Dublin brought against a leading software company and an international IT consultancy
  • Advising a global networking company on the EMEA wide employment aspects of a number of important global acquisitions
  • Advising a professional services company on a range of global employment law issues following a high profile merger
  • Successfully resolving a sensitive Employment Tribunal claim for a financial services organisation
  • Advising a provider of technology products on the termination of a senior employee of a recently acquired company
  • Advising a digital platform on the employment law aspects of restructuring its EMEA operations
