  • Employment

    Add to Portfolio

    Harry has a broad practice covering all areas of employment law and acts for both claimants and respondents. Harry has also received instructions in the Employment Appeal Tribunal and is comfortable with complex appellate litigation.  

    He has acted in cases involving a wide variety of issues and is particularly familiar with cases of unfair dismissal, discrimination, whistleblowing and pay claims.  

    Harry's recent instructions in the Employment Appeal Tribunal include: 

    British Telecommunications plc v Robertson (UKEAT/0229/20/RN) - Harry acted for the successful Respondent, appealing against the decision of the Employment Tribunal that the employee had been both unfairly dismissed and subjected to s.15 discrimination arising from disability. Auerbach J accepted that the Tribunal had failed to properly apply the test for causation under for the purposes of s.15 after reaching an unexpected finding in relation to disability. He also found that the Tribunal had erred in relation to the claim for failure to make reasonable adjustments, and dismissed that aspect of the claim without remitting it to the Tribunal.  

    Johnson vs Latchman (UKEAT/0239/19/OO) - Harry acted for the successful Claimant, responding to an appeal against a decision to extend the time for a Claimant to bring a claim for disability discrimination. Tucker J found that the ET's findings were open to it, and that, in any event, she would have made the same decision. 

    Godwin Jumbo v Zonal Retail Data Systems  (UKEAT/0275/19/LA) - Harry acted for the Respondent and responded to an appeal against a decision not to allow the Claimant to amend his claim to add four new causes of action where the Claimant had argued the ET had misapplied both the tests for extension of time and the balance of hardship test for applications to amend. 

    Le Page v East London NHS Foundation Trust (UKEAT0161/19/OO) - Harry represented the Respondent who successfully applied for costs following withdrawal of the Claimant's appeal. Eady J accepted the Respondent's submissions and awarded costs having found that the appeal was both unreasonable and misconceived. 

      Harry has recently been instructed in the following matters in the Employment Tribunal: 

    • Black vs FCO Services - A ten day trial for constructive unfair dismissal and disability discrimination in which Harry acted for the Respondent (led by Christopher Stone) and successfully restricted the scope of the Claimant's claim to the month prior to dismissal although the claim related to events took place several years beforehand. 
    • Smith v The University of Brighton Academies Trust – Harry acted for the Claimant in a 5-day whistleblowing claim. The Claimant was an Assistant Principal who complained that pupil safeguarding procedures were not being properly followed prior to being made redundant.  
    • Singh vs M&S plc - Harry acted for the Respondent in a seven-day hearing, dealing with numerous allegations of discrimination arising from the Claimant's disability which alleged to culminate with forcing the Claimant to resign. Harry successfully defended the Claim in its entirety. 
    • A highly contentious whistleblowing case (acting for the Respondent) in which anonymisation orders have been made and the disclosures are said to have been made in bad faith which was listed for an 8 day hearing prior to settlement. Harry was successful in defending the anonymisation order despite challenge by the Claimant. 
    • Wignall v Wincanton Group Ltd - Harry acted for the Respondent in a four-day hearing opposing a claim for disability discrimination. The majority of the Claimant’s claims were found to have been brought out of time and the Claimant’s claim for deduction from wages succeeded only in respect of a single day. 
    • Bhogal v The Culture Trip Ltd - Harry acted for the successful Respondent in a three-day hearing opposing a claim for unfair dismissal following a redundancy exercise involving collective consultation with 115 at-risk employees. 
    • Sterling v Genesis Research Trust and Professor Lord Winston  - Harry acted for the successful Respondents opposing an application for interim relief on the basis that the redundancy exercise leading to the Claimant’s dismissal was likely genuine. 
    • A claim for discrimination and harassment on the basis of the claimant's race in which an employee was subjected to racial bullying throughout his employment. The employee has suffered psychiatric injuries which remain unresolved and make it impossible for him to return to work. Harry is acting for the Respondent. 
    • Voronov v University Hospital Southampton NHS Foundation Trust - Harry acted for the Respondent in a four-day hearing dealing with the Claimant's allegation that he had not been hired because of his race, age or sexual orientation. Harry successfully defended the Claim in its entirety. 
    • Robertson v British Telecommunications plc - Harry acted for the Respondent in the two-day remedy hearing, dealing with issues of pensions loss and loss of earnings over a period of two years following dismissal, and was successful in obtaining judgment in the sum contended for by the Respondent which was roughly half the sum that the Claimant was seeking. 


    In addition to regular appearances in the Employment Tribunal and the Employment Appeal Tribunal, Harry’s practice includes drafting witness statements, assisting in grievance and disciplinary investigations, and advising clients both in writing and in conference.
