Kirsty Lewis


Kirsty graduated from the University of Manchester in 1994 with a BA (Hons) in Russian and Soviet Studies. After graduating, she worked for PriceWaterhouseCoopers in Moscow until 1997 before joining the City firm Lovells as a paralegal working in both London and Moscow until 2001. She then studied law and qualified as a solicitor in March 2004. In early 2006 she moved to Lyons Davidson where she gained extensive experience in Employment Tribunal work before joining Thomas Mansfield Solicitors in September 2006.

Kirsty is proficient in a number of languages including Russian and French.


Kirsty carries out a wide range of contentious and non-contentious employment work for both employer and employee clients.

Kirsty understands that when employers are making decisions, employment law is not their only consideration and she advises her employer clients in a way which suits their business including redundancies; disciplinary and grievance procedures. She takes a proactive approach to advising her employer clients and regularly works with them to identify training needs and update their employment documentation (contracts, policies and procedure). She works with her employer clients to resolve disputes in a way which suits the needs of the business and this includes: mediation; compromise agreements; and employment tribunal representation.

She also acts for employees in relation to all types of dispute including: unfair dismissal, constructive unfair dismissal, whistleblowing and discrimination claims. She works with clients to establish their priorities and help them identify the best way forward. This may involve bringing a grievance, going to an employment tribunal or negotiating with the employer to settle the matter outside of court.
