Even though employers are increasing investment in diversity and inclusion, three out of five U.S. employees have still witnessed or experienced discrimination based on age, race, gender or sexual orientation. That's according to a new survey released by Glassdoor which also found that the problem is not just a U.S. one with discrimination also found to be widespread in France, the UK and Germany. 55 percent of British employees also experienced it, along with 43 percent in France and 37 percent in Germany.
