Respect is a core principle of our work and a key reason for supporting a diverse and inclusive workplace. We value diversity and a respectful professional environment for all, regardless of sexual orientation, gender, color/race, age and physical/social conditions.

After five years promoting internal actions, we launched our Diversity and Inclusion Program (“DI Program”) in 2020, aiming to foster debates and to implement proactive measures inside and outside our office, focusing on the following themes: gender equity, racial equality, persons with disabilities and LGTBTI+ community. This initiative is supported by our Diversity and Inclusion Committee, which reports to our firm’s Board of Directors, and our Diversity and Inclusion Task Force, which reports to the Human Resources Department.

As a result of our DI Program, an annual schedule of actions was created to promote awareness for and inform all employees. The following actions were promoted during 2020-2021:

  • LGBTI+ Pride Day (2020): two webinars and a large communication campaign
  • Lesbian Visibility Day (2020): publication of two reviews
  • National Day of Struggle for Persons With Disabilities (2020): informative campaign
  • National Day for the Elimination of Violence Against Women (2020): informative campaign
  • Black Awareness Day (2020): two webinars and a large communication campaign
  • International Day of Persons with Disabilities (2020): one webinar and a large communication campaign
  • International Human Rights Day (2020): informative campaign
  • International Day for the Elimination of Racial Discrimination (2020): informative campaign
  • Trans Visibility Day (2021): one webinar
  • International Women’s Day (2021): one webinar and a large communication campaign
  • Nacional Day for the Elimination of LGBTIphobia (2021): informative campaign
  • LGBTI+ Pride Day (2021): one webinar and a large communication campaign
  • Nacional Day of Black, Latin American and Caribbean Women (2021): informative campaign
  • Lesbian Visibility Day (2021): a large communication campaign

Moreover, the following initiatives also occurred during the same period:

  • Creation of our Diversity and Inclusion Task Force (“DI Task Force”), the HR advisory staff group.
  • Conducting a demographic census of diversity and inclusion with all the employees
  • Conducting an Inclusive Leadership Workshop with all our partners and managers
  • Conducting selection processes without using demographic information such as age, address, race or sexual orientation
  • Joining “Empresas Sem Barreiras” (project that supports career advancement by making competitive hiring processes more inclusive for those Brazilians frequently facing racial discrimination)
  • Restructuring of our ethics and compliance policy to include diversity and inclusion topics
  • Implementation of a reporting channel
  • Joining “Incluir Direito” Project (initiative that creates a link between law firms and self-declared black law students, and offers greater professional opportunities to those students)
  • Joining United Nations Global Compact
  • Joining UN’s Women Empowerment Principles
  • Joining “Transempregos” (employment placement organization for Trans workers in Brazil)

Finally, it is worth mentioning that diversity and inclusion is one of the strategic basis of our firm and that a Diversity and Inclusion Committee was created to advise the Board of Directors on guidelines, best practices and strategic initiatives related to this important theme.
