It is obvious that stereotypes and biases are diversity obstacles, but it is not so simple to overcome them. It would be impossible to expect people to not have biases. The best way to overcome these obstacles is to increase diversity awareness:
One way to increase awareness in the workplace is for a company to create a diversity policy and make sure all employees know and understand it. This includes diversity training and having resources available for questions, as well as making it clear how and to whom issues should be escalated when necessary.
In order to increase diversity awareness, employees need to recognize the benefits of having a diverse workforce. Getting to know themselves and the people they work with is a big part of this. Companies often train employees on tasks or job-specific skills. Taking the time to train employees and teams to really know and understand each other is just as important.
Employees also need to be invited and encouraged to help change the business culture. If a company wants a diverse workplace, just hiring diverse people is not enough. The whole business culture must change and it starts by getting the employees involved and giving everyone responsibility.
