In California, Connecticut, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, Nevada, New Hampshire, Pennsylvania, and Washington, you need the consent of all parties participating in the conversation in order to record it. These twelve states are known as “two party consent states” so employees cannot secretly record conversations with other employees without their consent. In states without a two-party consent requirement, as long as one party gives consent, which can include the person recording the conversation as long as they actively participate, then the conversation can be legally recorded. If no party knows about the recording, then the situation may constitute wiretapping, which is subject to a different set of laws.
