Creating a culture where individuals and teams thrive

We are also transforming our culture to create an environment where individuals and teams are inspired to be ambitious for patients, accountable for impact, and to do the right thing, for each other, our communities, society as a whole and always for the patients we serve. Diverse perspectives lead to fresh, innovative ideas. We’re building an inclusive culture where the world’s talent can help transform medicine, together.

  • We have improved diversity, equity, and inclusion by recruiting and appointing diverse talent that mirrors the communities in which we live, work, and serve. By the end of 2023, 35.7% of senior leaders in the US were ethnically diverse at VP and above, compared with 31.3% in 2022.
  • We had 8.1% Black or African American leaders at VP-and-above compared with 8.6% in 2022. We had 6.4% Hispanic or Latinx leaders at VP-and-above compared with 6.4% in 2022. 
  • In 2020, we committed $10 million over 10 years to support the number of women and Black and Latinx students in Philadelphia entering STEM careers. More than 138,000 students of all backgrounds have benefited from GSK STEM equity grants provided to local non-profit organizations so far. 
  • In the US, we continue to engage with Historically Black Colleges and Universities, and Hispanic Serving Institutions, and our employee alumni, to
    encourage applications for our graduate and experienced hire positions and target recruitment campaigns to reach under-represented groups.
