It is not unlawful for a switchboard operator, or an officer, employee or agent of a provider of wire or electronic communication service whose facilities carry the communication, to intercept, disclose or use it in the normal course of employment while doing something that is a necessary incident to providing the service or to protecting the provider's rights or property; but a provider of wire communication service to the public may not use service observing or random monitoring except for mechanical or service quality control checks. An employer that runs its own email or phone system relies on this exception only for monitoring genuinely tied to operating or protecting that system.
