Simon Fenton , Partner
Simon joined Constantine Law in May 2018 from the employment team of a large national law firm. Simon qualified as a solicitor in 1993.
He specialises in company reorganisations, large scale redundancies, boardroom disputes, HR advice, employment law training, High Court injunctions, Employment Tribunal litigation(unfair dismissal and discrimination) and High Court injunctions. Simon has particular expertise in the tech, recruitment and hospitality sectors.
Simon’s first degree was in Management Science and he initially worked in pharmaceutical marketing at Boots and in the hospitality industry in Australia. Simon then spent 2 years in Hong Kong teaching at the British Council. He then decided to retrain as a lawyer and took another degree, this time in Law, before training at the City firm of Wilde Sapte (now SNR Denton). In his circuitous route to becoming a solicitor Simon picked up many useful skills particularly understanding the perspective of business and working in partnership with clients (rather than just advising and then backing off!)
In Chambers Legal Directory, he is rated as a Band One ranked lawyer, where they’ve said he is: “head and shoulders above the rest in terms of practicality of advice and understanding things from a business standpoint.” and “Clients praise his excellent guidance across a range of employment issues.”
The Legal 500 UK guide to outstanding lawyers nationwide names him in the elite ‘Leading Lawyers’ list and they say: “Fenton is praised for unique combination of depth, breadth and awareness.”
In his spare time Simon rides his bike (Land’s End to John O’Groats in 2017), and sits on the boards of Swings and Smiles (a charity providing services for children with special needs) and the Newbury Spring Festival (a classical music festival). However, what seems to take up most of his time is gaining weight, losing weight and parking!
