Board clarifies application of reverse onus and scope of reply evidence in unfair labour practice complaints.
During the hearing of an application for certification and related unfair labour practice complaints, the Board ruled on preliminary issues regarding the applicability of the reverse onus provision in section 89(5) of the Labour Relations Act and the scope of reply evidence.
The Board held that section 89(5) applies to allegations of employer misconduct affecting employment, including threats and interrogations, but not to general allegations of management interference that do not affect employment status.
The Board further ruled that the applicant, having elected to proceed first, could not split its case and must adduce all its evidence in chief, subject to a limited right of reply.
