Profile details

About David Mendel

David advises clients on executive incentive arrangements and employment law.

He is praised by clients for his thoughtful, calm and methodical approach to difficult legal issues. He regularly acts on some of the largest public M&A transactions in the UK market and is an expert on the impact of corporate activity on employees and share options. He has significant experience of advising on information and consultation obligations and the retention of key employees.

David acts for a large number of listed companies on their executive incentive arrangements and so is familiar with the intersection of legal issues, corporate governance, investor expectations and disclosure obligations. He also acts for large private equity houses on their management incentive arrangements. 

In addition to his expertise in employee incentives, David also has an active contentious and investigative employment law practice. He regularly conducts external investigations into allegations of employee misconduct and advises on difficult disciplinary and grievance issues. In recent years he has also secured injunctions to restrain the breach of restrictive covenants by former employees; successfully defended claims for breach of contract in the High Court and Court of Appeal; and has defended discrimination claims in the Employment Tribunal.

David is ranked in Chambers, both as part of our Band 1 Employee Share Schemes and Incentives Practice and our Employment practice, and is an active member of the Share Plan Lawyers’ Corporate and Regulatory Committee.

David is a member of the Remuneration Committee of New College, University of Oxford, an Ambassador to both the Freshfields Social Mobility Network and its Black Affinity Network, and a member of the firm’s LGBTQ+ network, Halo.
