Illinois Eavesdropping Act 14-3(j)Business telephone monitoring: notice to current and prospective employees and workplace signage A business using telephone monitoring or recording under this exemption must tell current and prospective employees that monitoring or recording may happen during their employment, and the notice must include prominent signage in the workplace.
Illinois Eavesdropping Act 14-2(a)(1)No surreptitious overhearing or recording of others' private conversations without all-party consent A person must not knowingly and intentionally use an eavesdropping device in a surreptitious manner to overhear, transmit or record any part of a private conversation to which that person is not a party, unless all parties to the conversation consent. For an employer this covers covert listening devices and silent monitoring of employees' private conversations, in person or by phone.
Illinois Eavesdropping Act 14-2(a)(2)No surreptitious recording of a private conversation one is party to without the others' consent A person must not knowingly and intentionally use an eavesdropping device in a surreptitious manner to transmit or record any part of a private conversation to which that person is a party, unless all other parties consent. Recording one's own calls or meetings openly, with the other parties aware, is not surreptitious.
Illinois Eavesdropping Act 14-2(a)(3)No surreptitious interception of others' private electronic communications without all-party consent A person must not knowingly and intentionally intercept, record or transcribe, in a surreptitious manner, a private electronic communication to which that person is not a party, unless all parties to it consent.
Illinois Eavesdropping Act 14-3(j)Business telephone monitoring: only for quality, training or research, with one active party's consent A business engaged in telephone solicitation by live operators (soliciting sales, receiving orders, helping customers use goods or services, or soliciting, administering or collecting bank or retail credit accounts) or in marketing or opinion research (live telephone interviews by a business whose principal business is polls and surveys) may use a telephone monitoring device to record or listen to those conversations by its employees only for service quality control, education or training of the employees or contractors doing that work, or internal research on it, and only with the consent of at least one active party to the conversation monitored.
Illinois Eavesdropping Act 14-3(j)Business telephone monitoring: personal lines, stop and destroy, no onward use A business using the exemption must give employees or agents access to personal-only telephone lines (which may be pay telephones) that are not monitored or recorded; must stop listening or recording at once, and destroy the recording as soon as practicable, when a monitored conversation turns out not to concern the solicitation or research work; and must not furnish anything obtained under the exemption to law enforcement, use it in any inquiry, investigation or administrative, judicial or other proceeding, or divulge it to any third party.
