Darren Isaacs works on complex international and cross-border HR projects, international business restructurings, as well as HR aspects of mergers & acquisitions.

Most of Darren’s clients are UK or US-based employers, and he focuses on cross-border and international HR projects. He is often instructed by clients who have large-scale EMEA matters that need managing, but he also regularly covers Australia and New Zealand.

Darren’s project work includes international M&A transactions, multi-country document reviews and cross-border litigation. Examples of Darren’s work include: advising a global IT business on the EU employment law aspects of its acquisition of a rival; leading the employment law team advising on a global financial services firm's insolvency in Europe; advising on the largest ever international roll-out of regulatory compliant bonus scheme rules for an international bank (60 countries); leading the European employment law team on a global demerger and separate listing; assisting a global "gig economy" start-up to establish operations across EMEA.

In addition to this, Darren also manages a domestic UK practice which includes advising local UK clients on all their day-to-day HR needs, as well as defending high-value employment tribunal litigation.

Darren has previously been awarded the International Law Office Client Choice Award for leading UK Counsel. He has also been ranked first in a survey of leading European M&A employment lawyers by Mergermarket. He is recognised as a leading practitioner by Chambers & Partners and is listed in “Who’s Who Legal 2021” as a leading labour & employment lawyer.
