We assist and advise on all issues of individual and collective employment relations.

Holmes specialise in employment litigation with a fifty-year track record of acting for insurance companies advising on employment claim protection policies.  We regularly assist our corporate M&A team on due diligence projects and other employment matters which arise during transactions.

We advise on complex employment issues, including employment injunctions, TUPE, interpretation of the regulatory framework, whistle-blowing and corporate immigration, as well as using an inter-departmental approach to addressing the specialist areas of health and safety and employee incentive schemes.

We work collaboratively with chairs, chief executives, in-house counsel, HR directors and HR professionals to find practical, effective and creative solutions to both every day and exceptional problems. Due to our extensive experience dealing with public sector bodies we have a deep understanding of the legal and constitutional issues faced by institutional clients.
