More than half of US employees, 61%, have witnessed or experienced some form of workplace discrimination based on age, race, gender or LGBTQ identity, according to a survey by Glassdoor.

Looking at specific forms of discrimination, the survey found that 45% reported witnessing or experiencing ageism, 42% reported racism, 42% reported gender discrimination and 33% reported LGBTQ discrimination.

Glassdoor’s survey included more than 1,100 US employees.

Younger workers, those between the ages of 18 and 34, are more likely to have experienced or witnessed the four types of discrimination.

However, 77% of employees responded that their companies employ a diverse workforce, and 64% said their companies are investing more in diversity and inclusion now than in past year.

Separately, Glassdoor found that job openings for roles related to diversity and inclusion in the US have increased 30% since last year with approximately 810 jobs open across the country.

Still, 55% of US workers believe their companies should do more to increase diversity and inclusion efforts, according to the survey. This sentiment was even more prevalent among Gen Z and millennial employees, with 62% saying their companies should do more.

In addition to the US, Glassdoor also surveyed employees in the UK, France and Germany. But the US had the highest percent of workers, 61%, reporting they witnessed or experienced discrimination in the four categories. In the UK, 55% said the same. The percent fell to 43% in France and 37% in Germany.
