NBA Commissioner Adam Silver, in a memo sent to all 30 NBA franchises and obtained by the Associated Press, said he wants teams to hire more women, especially in leadership and supervisory positions.

Silver urged teams to take some of the mandates that the Dallas Mavericks must now adhere to as an impetus to improve working conditions in their own organizations. Silver asked teams to thoroughly review the report that was released earlier this week about the Mavericks but stopped short of ordering the 29 other clubs to institute new policies.

His wishes were clear.

"Use this opportunity to make changes and create a dialogue within your organizations about workplace policies, procedures and respectful conduct," Silver wrote.

Incidents of sexual harassment and improper workplace conduct within the Mavericks organization were revealed in a Sports Illustrated article in February, and the NBA conducted a monthslong investigation, releasing a report Wednesday.

The league asked clubs to have what it is calling "Community Conversations" with employees within the next two weeks about the investigation and report about the Mavericks.

The league urged teams to consider making more than a dozen changes, including finding better methods for reporting and investigating harassment.

"Respect and integrity are core NBA values, and we all must work to ensure that they are reflected in the culture and workplaces of our organizations," Silver wrote.
