David Greenhalgh

David worked for Joelson as a junior lawyer twenty years ago leaving to run several of his own specialist firms.  David returned to the Joelson fold in 2016 bringing with him 25 years of experience of litigation and employment and of running several successful law firms (H2O Law and Twenty Twenty).

David heads up the Joelson employment team advising employers, management teams and senior executives.  Both the team and David have been recommended in the prestigious Legal 500 independent guide to the UK legal profession.  David has also been listed in the Super Lawyers Guide. He is also a regular contributor to the press on employment/HR matters.

In advising clients on their employment issues David utilises his background in ground breaking heavyweight litigation (including securing victory for the families of the Omagh bombing victims in their landmark civil action against the Real IRA and for terrorism victims in the Almog v Arab Bank litigation).  David scored an important victory for UK employers in the Sunrise Brokers v Rodgers case in the High Court, Court of Appeal and Supreme Court, where he obtained an injunction to enforce restrictive covenants blocking an employee from joining a competitor for a lengthy period.

David is a trustee of Noah’s Ark Childrens’ Hospice (running its HR subcommittee) and is a Court member for the Guild of HR Professionals.


David gives “unstuffy and commercial” employment advice to employers across a wide range of industry sectors.  His specialisms for employers include post termination restrictions and injunctions, defending tribunal claims, exit tactics and running investigations.  He is currently working with employers clients from the insurance, media, professional services and fund management sectors.

David also regularly acts for senior level executives where his specialisms include defending misconduct allegations and related disciplinary action, bringing tribunal claims, bonus claims and high value exit negotiations.  He gives tactical advice with a focus on reputation protection.

Key matters include

  • Acting for Sunrise Brokers in their well publicised High Court/Court of Appeal victory for UK employers.
  • Negotiating high value exit packages for a number of financial services senior executives.
  • Advising a leading insurer on a revamp, variation and successful roll out of new employment documentation.
