Business, Structure
Mayer Brown International LLP (the Firm, we or our) is a limited liability partnership (registered in England and Wales with number OC303359) and authorized and regulated by the Solicitors Regulation Authority, with SRA number 369822.
The Firm is part of Mayer Brown, a global legal services provider comprising associated legal practices that are separate legal entities.
Supply Chains
As an office based business the Firm's supply chain includes facilities for the benefit of clients and staff, such as cleaning, security and catering.
We consider our supply chain to be typical of a global legal services provider, involving supplies such as office goods and equipment and supplies connected with business development needs hosted by the Firm, which may include training events.
Policies
We are and remain committed to achieving the highest standards of ethical conduct and to ensuring that we, our lawyers, employees and others who may provide services to the Firm or on the Firm's behalf, act in compliance with all applicable laws, which includes applicable laws prohibiting slavery and human trafficking.
We value our people and seek to create a work environment where everyone is valued and treated with dignity and respect. Everyone has the right to work without fear of harassment and we encourage reporting of inappropriate behavior and operate a strict policy of non-tolerance towards victimization of anyone making a report in good faith.
We do not engage with suppliers whom we know or believe fail to operate to similar ethical standards and treat their staff with respect.
Risk Assessment
In line with our legal and ethical obligations we continue to address slavery and human trafficking risks in our business and supply chain. Based on the nature of our business, our long standing relationship with key suppliers and our processes regarding new suppliers, we consider the risk of modern slavery in our supply chain remains relatively low. However, we are not complacent and recognize the need for continued vigilance regarding such risks.
Due Diligence
In the year ending 30 April 2025 we have continued to manage the risk of Modern Slavery occurring in our supply chain through:
- Continuing to identify, on a risk-approach basis, suppliers in areas of perceived greater risk (for example, security, catering and cleaning). When we meet those suppliers, modern slavery concerns or breaches are addressed. Should any issues be reported, in particular any breaches, we would require them to be dealt with swiftly and appropriately.
- Continuing to require new suppliers, when first added to our system as suppliers to complete a supplier information form, which contains a statement by the relevant supplier affirming compliance with applicable modern slavery laws.
- Continuing application of our Procurement Policies and Procedures and Supplier Code of Conduct.
Training
We recognize the importance of training in raising awareness to ensure all staff remain vigilant and to ensure those with direct procurement roles fulfil their responsibly.
All joiners are provided with an information pamphlet on modern slavery and an annual update is provided for senior managers on any developments in the legislation or potential risk areas in the Firm's supply chain to which they should have special regard.
Measuring Effectiveness
As a result of taking the above steps for the year ended 30 April 2025, no breaches of the modern slavery legislation by our suppliers have been reported to us or have otherwise come to our attention.
Approval
This statement is made pursuant to section 54 of the Modern Slavery Act 2015 with respect to the financial year ending 30 April 2025 and sets out the steps the Firm has taken in that period to continue to address slavery and human trafficking risks in its business and supply chain.
