The firm is one of 12 global organisations to be named in the list that highlights multinational businesses for the progress they have made in LGBT equality within the workplace. The list is compiled from Stonewall's Global Workplace Equality Index which ranks organisations on how they uphold inclusive values across their global networks.
Earlier this year the firm was the highest ranking law firm in Stonewall's Workplace Equality Index, ranking second out of the hundred most LGBT-friendly companies in the UK.
Senior partner at Pinsent Masons, Richard Foley, said: "Being genuinely valued and respected at work is empowering for the individual and the business. We want to create a working environment that values the power of diversity and allows all of our people to bring their whole selves to work. This is essential to establishing trust and rapport not only across our own workforce but with clients, suppliers and the wider community.
"As a global employer we recognise the complexity of different attitudes and cultures which our LGBT employees experience in the many countries in which we operate. We are committed to ensuring that our inclusive culture extends across the entire organisation. Working with Stonewall has enabled us to adapt our approach so it is respectful to different cultures but does not compromise our values."
Organisations included in the list are assessed against a set of best-practice criteria across nine areas of employment policy and practice. Stonewall examines both global working structures and operational country activity.
Chief executive of Stonewall, Ruth Hunt, said: "Pinsent Masons and all of our Top Global Employers, have demonstrated a real commitment to ensuring that all lesbian, gay, bi and trans staff and stakeholders feel included at work. These businesses truly are at the forefront of driving global LGBT inclusion in the workplace, and between them reach over 1.5 million people.
"There is so much left to do to ensure that lesbian, gay, bi and trans employees feel able to be themselves at work no matter where they are. Stonewall's Top Global Employers continue to not only roll out the best practices to achieve that, but are also great examples of businesses that imbed a culture of inclusion that is integrated across all of the work that they do."
