(b) the affected employees have voted, by ballot or by an electronic method, on whether to approve the variation and, of those who cast a valid vote, a majority approved the variation; and
(c) there are no other reasonable grounds for believing that a majority of the affected employees who cast a valid vote did not approve the variation; and
(d) each employee organisation covered by the agreement, that is entitled to represent the industrial interests of one or more affected employees, agrees to the variation.
