High Court Litigation - Employment

Our employment law experts have acted in some of the highest profile, largest value and most complex commercial employment disputes in recent years, for both corporates and individuals. We are frequently instructed on complex disputes which involve expedited proceedings and/or cross-jurisdiction litigation.

We are regularly instructed by clients to:

  • obtain injunctions to enforce garden leave clauses, non-competes, and other restrictive covenants;
  • resist applications for injunctions or to challenge the enforceability of those obligations which unreasonably prevent competition;
  • litigate claims involving breaches of fiduciary, statutory or contractual obligations, including multi-million pound bonus disputes;
  • recover stolen confidential information and trade secrets and prevent publication, dissemination, or use by competitors or former employees, including applications for search orders, forensic imaging and delivery up orders.

Clients come to us for our market-leading expertise in these disputes. We have extensive experience and a deep understanding of the unique pressures and commercial drivers which enables us to identify an approach that can resolve cases strategically and quickly. Our lawyers are experts at helping clients navigate litigation whilst preserving and enhancing reputation.
