Dealing with Addiction in the Workplace

Lets say for instance that an assistant director used the agency's internet to pull up pornography and to solicit women for prostitution. This has been taking place for at least six months and has been occurring regularly at least three to four times a week. One day, the assistant director schedules an appointment with Human Resources and discloses that he has an addiction to pornography and a sexual disorder that contributes to his desire to engage in sexual behaviors with prostitutes and that he has been using the company equipment to support his addictions.

Do we terminate him? Do we call in the media and disclose this information? Do we refer him to EAP? How should we address this situation with the assistant director? Is a situation worse if we find out or if we are told? Should the manner in which this issue is addressed now differ?
