If a coworker accesses another coworker's email client and reads a message in the outbox, what are they violating?

The situation described involves accessing another person's email client without their permission and reading a message that is in the outbox. This act can violate the Wiretap Act, which is part of the Electronic Communications Privacy Act. The Wiretap Act prohibits the intentional interception of electronic communications, and although the outbox may not be in transit, the access and reading of these communications without authorization demonstrates a breach of privacy expectations that the act aims to protect.

While the other options relate to different aspects of privacy and data protection, they do not specifically address the unauthorized interception of electronic communications. The Stored Communications Act applies to the unauthorized access or disclosure of stored electronic communications, which could also be relevant in some contexts but does not directly cover the interception aspect in the same way as the Wiretap Act. The Privacy Act primarily deals with the management of personal information held by government agencies, and HIPAA governs the privacy of health information, which is not related to email communications in this case. Therefore, the Wiretap Act is the most applicable law concerning unauthorized access and interception of electronic communications like emails.
