Any party seeking to challenge the status of a unit representative may submit information to the SERB. The SERB shall determine whether the information provides a reasonable basis to constitute that a majority of the unit wishes to be represented by a different representative or a majority of the unit decides no representation. If the SERB so determines, it shall adopt a process it believes warranted to ascertain the majority's choice of representation, including by the submission of authorization cards or election, unless such process has been undertaken in the previous two years.
