Slattery, who made number 50 on the list, said she worked to raise awareness of sexual orientation across Sodexo’s international business, both as part of the company’s global LGB network leadership team and the global pride group.
She is also on the board of the Gay and Lesbian Equality Network, a policy and strategy focused non-government organisation in Ireland looking to introduce a workplace charter on how lesbian, gay and bisexual diversity helps drive business excellence.
Last year she was highly commended in the Diversity Champion of the Year category at the European Diversity Awards and joins senior business leaders such as Burberry chief executive Christopher Bailey and celebrity retail expert Mary Portas on the Top 100 list.
Slattery said: “I’m very honoured to be included in an exceptionally heavy-hitting list of high-profile business leaders.
“People are at the heart of making a company successful so it’s essential there are visible role models to help create an inclusive workplace where everyone can thrive.”
