Sarah has considerable experience advising clients on the full range of both contentious and non-contentious employment matters. She regularly advises clients on the complex and sensitive issues arising out of the acquisition of a business and the harmonisation of that business into the wider corporate structure both locally and cross border.

This involves advising on implementing new service agreements and benefit packages for senior executives, employee and trade union consultation, and post-completion integration. Sarah also regularly appears in and advises clients on Employment Tribunal matters, particularly in the areas of discrimination and whistleblowing, and in respect of bonus claims. She also has significant experience of managing cross-border projects.

Sarah is a regular contributor to employment journals such as Practical Law, and is frequently quoted in the press. Prior to working at Allen & Overy, Sarah spent two years as an in-house employment lawyer where she developed a practical and commercial approach to problem solving in a unionised workforce.

Sarah Henchoz regularly posts on subjects such as discrimination and atypical working for Allen & Overy’s Employment Talk blog.
