Paul O'Callaghan (2008) LLB (Hons)

Membership Status: Barrister - Full Member

General Information

Paul O'Callaghan joined Clerksroom in 2013 having previously practised as a solicitor-advocate with a national firm of solicitors.

Paul was called to the Bar at Gray's Inn back in 2008 and he is now fourteen years Call (where do the years go)! Paul is a specialist employment and civil barrister. 


Paul is a member of the Employment Lawyers Association (ELA) and a specialist employment lawyer with a national practice encompassing the full range of employment law issues.

Paul regularly appears at tribunals nationwide but he prides himself on a conciliatory approach to employment disputes and he is pleased to say that the vast majority of cases that he deals with settle amicably without the need for a trial which ultimately saves time and costs.

Paul's employment work is generally split at 75% Claimant and 25% Respondent. Paul has succesfully handled claims against major multi-national companies as well as public sector organisations. Paul offers advice in writing, by telephone or remotely via video call as well as in person.

Paul is regularly instructed by major insurers to provide legal opinions and he also provides advice and assistance to employees and employers involved in disciplinary and grievance procedures. Paul is adept at document drafting and he aims to return papers within seven days.

Paul recently acted in a group litigation case against an international bank represented by a Magic Circle law firm and Queen's Counsel.  Paul was able to negotiate a settlement on behalf of the group in excess of £400,000.

Recent successes include:

Whitbourn, Atherton, Neto -v- Key People Limited (1) Just Recruit Group Limited (2)

I represented three Claimants on a direct access basis from day one through to a successful conclusion after a fully contested trial. The Tribunal found that all three Claimants were unfairly dismissed and Miss Whitbourn was discriminated against on the grounds of sex. The total award was in excess of £200,000 and the case was also reported in the national media. Both Respondents were legally represented by expensive London solicitors who repeatedly threatened my clients with costs.

Phillips -v- Pontcanna Pub Company Limited

I was instructed by local solicitors and represented a young female bartender who was violently choked by a colleague at a work Christmas Party. The Claimant complained to management who turned a blind eye to the perpetrator’s conduct and sought to downplay the incident, even making jokes about it. The Claimant resigned and brought a claim of constructive unfair dismissal. Her claim was successful following a trial where the Respondent was represented by solicitors and counsel who threatened to make an application for costs if the claim was not successful. The case was widely reported in the media.

Professor T Ahmed -v- United Lincolnshire Hospitals NHS Trust

The Claimant instructed me directly and I represented him at a 10 day hearing before the Nottingham Employment Tribunal. The Claimant’s claims of unfair dismissal, direct discrimination (race) and victimisation were upheld following a botched disciplinary hearing. The Respondent NHS Trust fought the claim vigorously and sought to discredit the Claimant’s evidence at trial but the Tribunal were highly critical of the Respondent’s procedure in their judgment. The case was reported in the media and a remedy hearing will be listed to determine compensation which is likely to be significant.

Ahmed -v- Medexpress Limited

I represented the Respondents on a direct access basis and successfully defended multiple claims including constructive dismissal, discrimination on the grounds of race and sex as well as whistleblowing detriment during the course of a ten day trial. The case was reported in the national media and the judgment was circulated to the parties recently and is due to be published the near future.

Dear xxxxxxxx, You had informed me that Paul was a very good barrister, seeing him in action I would say excellent. Paul is also very honourable, kind, calm and composed which gave me a lot of confidence over the course of the 6 day hearing. I do not know yet the outcome of my case – whatever happens, Paul was just brilliant, and I’ll always be truly grateful for his support. Thank you very much for kindly recommending him. Kind Regards
