Ben Amunwa is an experienced employment lawyer who advises and assists employers and employees on grievances, disciplinary matters, dismissals, discrimination, sexual harassment, whistleblowing, business transfers, wages and holiday disputes, union matters and modern slavery.
Ben has conducted complex trials in person and remotely via video-link, including several 15-day discrimination, victimisation and whistleblowing trials cases involving thousands of pages of evidence and multiple witnesses.
Ben’s experience includes settlement negotiations, drafting (employment contracts, internal policies and pleadings) and representation in Tribunals, civil courts and before regulatory panels. He primarily focuses on the corporate, legal and public sectors but also accepts instructions from other fields or industries.
He provides practical and strategic advice, negotiation skills and effective representation at preliminary hearings, multi-day trials and appeals.
Owing to the breadth of Ben’s practice, clients often request him when atypical points arise, such as wasted costs, self-incrimination, breaches of disclosure duties, data protection or immigration issues. Unusually, he has cross-examined numerous solicitors (including partners at magic circle law firms) in his employment trials, as well as questioning executive witnesses over sexual harassment allegations.
Ben has given training to employment law practitioners and has written an acclaimed guidebook for the Law Centres Network on employment rights (described by a Head of Employment as “incredibly useful and thorough”), plus many articles and blogs.
Ben Amunwa analyses the case of Adekoya & Ors v Heathrow Express Operating Company Ltd [2024] EAT 72, which found that the Employment Tribunal erred when it dismissed the claimants’ claims for breach of contract challenging the withdrawal of post-termination travel benefits from them in reliance on a contractual agreement that had not been sent to the claimants.
Ben considers the resulting practical implications for practitioners, employers and employees.
Ben Amunwa analyses the case of Secretary of State for Business and Trade v Mercer [2024] UKSC 12, in which the UK Supreme Court hands out a victory for the protection of Trade Union freedoms and workers' rights, finding the UK to be in breach of ECHR article 11 as section 146(2) of TULRCA fails to provide protection from detriment for workers participating in lawful strike action.
Ben Amunwa analyses the case of Omooba v Michael Garrett Associates Ltd (t/a Global Artists) & Anor [2024] EAT 30, in which the EAT upheld the Tribunal’s judgment, including its key finding that where a protected belief forms part of the context but not part of the reason for a decision, that will be insufficient to establish religion or belief discrimination.
Ben Amunwa has a standout practice in public and equality law, including cases challenging inadequate provision of education and housing. He draws on his background in NGOs and advocacy groups to handle strategic litigation, primarily on behalf of vulnerable clients and asylum seekers.

Chambers 2024/Administrative and Public Law/London Bar

Chambers 2023/Administrative and Public Law/London Bar
"He is an extremely clever barrister, who provides excellent drafting and is also great with clients." "He is collaborative, responds quickly and is very dedicated."
Chambers 2022/Administrative and Public Law/London Bar
"I will never understand how on earth Ben absorbed so much detail… In cross-examination of the other side’s witnesses, Ben very artfully led those witnesses to make admissions that they had avoided. He blew their case wide open, making them admit that they should have taken steps to retain data, that they should not have deleted electronic data. These were witnesses at the top of the organisational chart."
