This paper first outlines studies of the measured benefits of diversity, and the different ways in which they manifest, in order to emphasize its importance. Demographics data from international astronomy organizations is presented to illustrate the current state of the workforce in observatories and within observatory operations. Finally, a much-needed focus is placed on inclusion in the workplace. We review why creating an inclusive environment is important for the success of maintaining a diverse organization. We discuss how different programs implemented at astronomical observatories contribute to creating an inclusive environment, and detail real-world examples of these efforts taking place in these institutions. The goal is that these strategies can be adapted to benefit other similar organizations.
